@Mishu007,

This is what I was afraid of. Links to tutorials and or articles that do not work. I have tried to produce the same exact thing and all I see are errors and issue with Ajax. I was using ASP.NET 4.5 and I had to switch to 4.0 because that is one of the recomendations in the error or switch to ScriptManager instead of ToolScriptManager but no luck either.

I'm going to post the codebehind and webservice along with the AJAX errors I'm receiving. I could really use some help with this. I have searched google for almost and entire day and no good tutorials out there on this at least none that I can find that work :(

@jinsonaf,

The link you supplied has to do with authentication against AD. I don't need that, I need to auto populate users from AD as you type them out in a TextBox control. Just as when you enter search words in Google, the words start to appear as you type.

We can implement Autopopulation with JQuery,

refer this link

http://www.aspsnippets.com/articles/using-jquery-autocomplete-plugin-in-asp.net.aspx

In .ashx, write a code to retrive Users from AD.

@jaqssidurala,

Ok, I understand the jquery part at least it seems self explanatory. The problem that I still need help is the code for AD retrieval. I simple need to populate the list of all users in that textbox control as you type in the name it will search AD and show list of possible matches to choose from. That is what I really need help with.

Check following

http://www.nerdliness.com/article/2008/02/05/pulling-data-active-directory-asp-net-ajax-autocomplete-extender

http://stackoverflow.com/questions/11129769/active-directory-web-service-and-autocompleteextender

@CodeCruiser,

I implemented the second link you supplied and it did not autocomplete as I typed in the TextBox Control. I did not retrieve anything from Active Directory. I also did not receive any sort of errors. Please take a look at my CodeBehind and Markup.

Also, the name of my AD server is called occo.local

>ServicePath="~/App_Code/ADS.cs">

Service path needs to be a URL of a webservice which usually ends in asmx extension not cs.

@CodeCruiser,

Ok, I now have the ServicePath set to the following below. But when I try to type in a username, firstname, and or lastname. Nothing is getting displayed :(

ServicePath="~/ADS.asmx"

If you type that URL in, does it browse to the webservice? Is the webservice at same level as your page in IIS? If you set a breakpoint on findEmp method, is it being called?

>>If you type that URL in, does it browse to the webservice?
If I type in the site on my local browser I see the following URL below and Screenshot.

URL in Browser window after typing in the webservice URL.
http://localhost:51190/AD%20test/ads.asmx?op=findEmp

Screenshot below after typing in the URL to the webservice below.


>> If you set a breakpoint on findEmp method, is it being called?
If I set a breakpoint on the findEmp method nothing happens. There are no errors shown in Visual Studio. It appears that the breakpoint did not even exist. Just to be certain I applied a break point on the line below.

Breakpoint was set on this line.
public string[] findEmp(string prefixText, int count)

Breakpoint needs to be set on a line within the function not the function declaration line itself.

Is your page within "AD test" folder as well?

Hi CodeCruiser,

First let me know you tremendously for your help with this post. This is a topic that I know very little about. I never needed to do anything like this until now and it's very unclear and hard to follow tutorials on the web. Which leaves me to EE for this topic. So thank you very much for your continued help...

>> Breakpoint needs to be set on a line within the function not the function declaration line itself.
I added multiple breakpionts. But no matter where I set the breakpont at nothing ever popups up to display anything. Nor are there any errors :(


>> Is your page within "AD test" folder as well?
I'm going to list my structure of my web site below. This way you can see how and where my files are located.

rootDirectory
  App_Code
      ADS.cs
  ADS.asmx
  index.aspx
  web.config

I have tried to create a sample myself but could not get the webservice approach to work. Instead I have used PageMethod approach. I used following code which worked (breakpoint hit)

>First let me know you tremendously for your help with this post.

Assuming you meant "Thank", I would be glad if this works for you.

Hi CodeCruiser,

Yes, I meant, Thank you :) I really appreciate the help.

Ok, so I added the code you suggested on my index.aspx page and CodeBehind but when I run the page I don't see anything getting populated in the TextBox as I type. I'm also confused as how this will work without adding any code to the Page Methods. I also noticed you removed the webservice from the AutoExtendor Ajax control.

Also, I see you have this in the index.aspx page Inherits="WebApplication3.index". Did you forget to include the code for webapplication3.index?

>I don't see anything getting populated in the TextBox as I type

That's because there is nothing being returned from the method. Does it hit a breakpoint?

>I'm also confused as how this will work without adding any code to the Page Methods.

I removed that code because I don't have any AD on my computer and it was a demo.

>I also noticed you removed the webservice from the AutoExtendor Ajax control.

Yes. Removing that makes it work with page method.

>Also, I see you have this in the index.aspx page Inherits="WebApplication3.index". Did you forget to include the code for webapplication3.index?

index is the name of the page. WebApplication3 has to be added as it was the namespace. Change that to your own project name.

Sorry, I'm confused. The name of my page that contains the Ajax control and codebehind is called index.aspx. So i'm not sure what I should call the namespace.

Below is what I currently have for my CodeBehind and Markup. I also set a breakpoint on each line of the code you supplied in the codebehind but when I run the page nothing is error shown from the textbox nor are there any errors or messages shown from visual studo. It's like the breakpoints are not even working.

Change it to

Inherits="index"

That is what I had in my last post. "Inherits="index"" and that didn't do anything differently. Take a look at my post 38722012.

As I said, it will NOT do anything because there is no code in there.

Set a breakpoint and see if that breakpoint gets hit. If it does, put your original code backin and see if it does something.

Ok, I set a breakpoint on every line and the breakpoint did NOT get hit.

Ok. It looks like it does not want to work then. It worked in my sample.

Any other ideas CodeCruiser.

I was able to get the following below to work but with a couple of problems.

Issues below:
  - The data populated once you type in the textbox control disappears if I try to select an entry using my mouse or arrow keys.

  - Still need help with connecting this to the webservice.

@Mishu007,

I tried your solution to the link you supplied and did NOT have any luck at all. No errors and no data got populated in the TextBox. Do you know how to implement autocomplete without using AJAX? Do you know how to get this to work using jquery autocomplete and pointing to webservice? Please no links or tutorials. That takes to much time and leads to no were.

Hi,

Sorry for long delay....

You can use jQuery to autocomplete the textbox. To use jquery you must have a web service that will transform the AD users into json and then put that address of the method into the jquery definition for autocomplete and all should work ok.

I'm sorry I know you said no links but unfortunately I can't provide a full example right now.

Here is a link that I think will be fast and easy to understand and implement.

ASPX Autocomplete using Jquery UI

Sorry again for not providing a sample myself.


Regards,
Mishu

@Mish007,

Thanks for replying back. I have been looking at your first post with the link at the bottom solution and I have been having a hell of a time trying to get that to work. I tried once again just now after adding jquery autocomplete but with no success. Would you please be able to look over my ADS.asmx code to see what it's not populating results from my Active Directory? I know you don't have access to my Active Directory but was hopiong you may see someting that may help me out. I would really appreciate it. I have been able to populate data using the jquery autocomplete will sample data just not with my ADS.asmx code.

The ADS.asmx code below is from your link that you supplied to me in your first post. It was taken from the solution except at the bottom of that page. I need to be able to retrieve First and Last Names from AD when the user starts to type in the TextBox control.

Hi,

If you are using the JQuery approach you can use it like this (from my second example link):

$('#<%= txtName.ClientID %>').autocomplete({
                source: function(request, response) {
            $.ajax({
                url: "ADS.asmx/findit",
                data: "{ 'prefixText': '" + request.term + "' }",
                dataType: "json",
                type: "POST",
                contentType: "application/json; charset=utf-8",
                dataFilter: function(data) { return data; },
                success: function(data) {
                    response($.map(data.d, function(item) {
                        return {
                            value: item
                        }
                    }))
                },
                error: function(XMLHttpRequest, textStatus, errorThrown) {
                    alert(textStatus);
                }
            });
        }, 
        minLength: 2 
    });

Also you may need to change the findit declaration to have only one parameter the string one, or map it in the data parameter in the jQuery definition.

I'm very sorry but I can't test this right now because I'm on the run ... but it should work...

Also have a look into this article regarding AD query using C# Howto Almost Everything In Active Directory via C#, especially at the Translate the Friendly Domain Name to Fully Qualified Domain.

public static string FriendlyDomainToLdapDomain(string friendlyDomainName)
{
    string ldapPath = null;
    try
    {
        DirectoryContext objContext = new DirectoryContext(
            DirectoryContextType.Domain, friendlyDomainName);
        Domain objDomain = Domain.GetDomain(objContext);
        ldapPath = objDomain.Name;
    }
    catch (DirectoryServicesCOMException e)
    {
        ldapPath = e.Message.ToString();
    }
    return ldapPath;

@Mishu007,

Ok, thanks. I added the jquery that you supplied and I did not have any issues with the jquery this time. But, I still cannot get any data to autocomplete with the ADS.asmx code that I have. I tried your code snippet and looked at the URL that you supplied but it did not supply any data to autocomplete either :(

I know your on the run but could you possible assist when you have time? It would be greatly appreciated. When I added the code you supplied I had redlines on "string" and a red line on "DirectoryContext" and also a red line after the "}" character. Each re line says the following below. What I need is when the user enters an employees last name and or first name that it will autocomplete a list of users in AD. Then the user can select with his/her mouse to select the correct user from autocomplete.

Error:
Expected class, delegate, enum, interface, or struct

Hi,

Here is what I got to find ad users that starts with a string...

For framework 2.0:

public static string GetDomainDN(string domain)
        {
            DirectoryContext context = new DirectoryContext(DirectoryContextType.Domain, domain);
            Domain d = Domain.GetDomain(context);
            DirectoryEntry de = d.GetDirectoryEntry();
            return de.Properties["DistinguishedName"].Value.ToString();
        }

        public static List<string> GetADUsers2_0(string searchTerm)
        {
            List<string> res = new List<string>();
            // define a directory searcher for your default context
            string searchRootLDAPPath = GetDomainDN(Domain.GetCurrentDomain().Name);
            using (DirectoryEntry defaultDE = new DirectoryEntry(String.Format("LDAP://{0}", searchRootLDAPPath)))
            {
                // define searcher - search through entire subtree, search for users 
                // (objectCategory=Person)           
                using (DirectorySearcher dsAllUsers = new DirectorySearcher(defaultDE))
                {
                    dsAllUsers.SearchScope = SearchScope.Subtree;
                    dsAllUsers.Filter = String.Format("(&(objectCategory=person)(objectClass=user)(cn={0}*))", searchTerm);

                    // get the results
                    SearchResultCollection result = dsAllUsers.FindAll();

                    foreach (SearchResult searchResult in result)
                    {
                        res.Add(searchResult.GetDirectoryEntry().Name.Remove(0, 3)); //removing the CN=
                    }

                }
            }
            return res;
        }

Also include the assembly System.DirectoryServices into the project.

For .Net Framework 3.5 and above (works both solutions here):

private static List<string> GetADUsers(string searchTerm)
        {
            List<string> res = new List<string>();
            using (var context = new PrincipalContext(ContextType.Domain, Domain.GetCurrentDomain().Name))
            {
                // create a principal object representation to describe
                // what will be searched 
                UserPrincipal user = new UserPrincipal(context);

                // define the properties of the search (this can use wildcards)
                user.Enabled = true;
                user.Name = String.Format("{0}*", searchTerm);

                // create a principal searcher for running a search operation
                using (PrincipalSearcher pS = new PrincipalSearcher())
                {

                    // assign the query filter property for the principal object 
                    // you created
                    // you can also pass the user principal in the 
                    // PrincipalSearcher constructor
                    pS.QueryFilter = user;

                    // run the query
                    PrincipalSearchResult<Principal> results = pS.FindAll();
                    
                    foreach (Principal result in results)
                    {
                        res.Add(result.Name);
                    }

In order for this to work you have to add reference to System.DirectoryServices.AccountManagement.

I've tried this in my current domain and it works great.

Try and use this in the web service to see if it's working or even in a console application to test it out. Maybe you need some credentials to access the AD.

Hi,

Here is an example I've modified for you and it works ok on my domain.

I don't remember exactly where I got the initial sample. It only had the employee list. And one of the problem was that I was setting the static on the web method.

WebService.cs

public static string GetDomainDN(string domain)
    {
        DirectoryContext context = new DirectoryContext(DirectoryContextType.Domain, domain);
        Domain d = Domain.GetDomain(context);
        DirectoryEntry de = d.GetDirectoryEntry();
        return de.Properties["DistinguishedName"].Value.ToString();
    }

    [WebMethod]
    public List<string> GetADUsers(string term)
    {
        List<string> res = new List<string>();
        // define a directory searcher for your default context

        string searchRootLDAPPath = GetDomainDN(Domain.GetCurrentDomain().Name);
        using (DirectoryEntry defaultDE = new DirectoryEntry(String.Format("LDAP://{0}", searchRootLDAPPath)))
        {

@Mishu007,

I added your example and opened it in Visual Studio. I did not modify it and when I ran the application I get the same issue as before. When I type two characters I get a Javascript popup window. Please see the attached screenshot. If I type only 1 character then everything is fine. It's only when I type 2 or more characters.

Hi,

Replace the web service method with this:

 [WebMethod]
    public List<string> GetADUsers(string term)
    {
        List<string> res = new List<string>();
        // define a directory searcher for your default context

        try
        {
            string searchRootLDAPPath = GetDomainDN(Domain.GetCurrentDomain().Name);
            using (DirectoryEntry defaultDE = new DirectoryEntry(String.Format("LDAP://{0}", searchRootLDAPPath)))
            {
                // define searcher - search through entire subtree, search for users 
                // (objectCategory=Person)           
                using (DirectorySearcher dsAllUsers = new DirectorySearcher(defaultDE))
                {
                    dsAllUsers.SearchScope = SearchScope.Subtree;
                    dsAllUsers.Filter = String.Format("(&(objectCategory=person)(objectClass=user)(cn={0}*))", term);

                    // get the results
                    SearchResultCollection result = dsAllUsers.FindAll();

                    foreach (SearchResult searchResult in result)
                    {
                        res.Add(searchResult.GetDirectoryEntry().Name.Remove(0, 3)); //removing the CN=
                    }

                }
            }
        }
        catch (Exception ex)
        {
            res.Add(String.Format("Error: {0}", ex.Message));
        }

        return res;

The error message occurs when you are not in a domain. At least in my part. At work where I am in a domain works great.

Hi Mishu007,

Ok, I modified the code to what you posted above. Unfortunetly I get the same result. I see that you mentioned that I need to be in my domain for this to work. I'm actually working from home on my personal laptop using a VPN to my network since I started this post. I go back to the office this Thursday so I can see if it works then. But I was wondering would it work if I supplied the LDAP path rather than how it is now, would that make a difference since I'm working from home? We have some users who use they computer issued by us but work from home. Will that be a problem for them?

Also, what is the difference to the following below?

What I was trying to use from the tutorial:
"LDAP://n-acdir:389"

What you are using:
"LDAP://{0}"

Hi,

You could specify directly the LDAP connection string but I advise to use this method to return the qualified domain name.

public static string GetDomainDN(string domain)
    {
        DirectoryContext context = new DirectoryContext(DirectoryContextType.Domain, domain);
        Domain d = Domain.GetDomain(context);
        DirectoryEntry de = d.GetDirectoryEntry();
        return de.Properties["DistinguishedName"].Value.ToString();
    }

Also try to debug the web service method and see what it returns. If you use the last code from my last post you should get an error it will return it as auto complete.

I don't think that the port number is necessary unless you configured the domain like so.

Mishu

Hi,

Can you debug the web service method? I mean does it enter in the method? Maybe it's an AD error.

I've noticed that in the web service the class name is ads and in the jQuery is ADS.asmx.

Also write the correct path in the jquery definition of the web service file in order to work ok.


Regards,
Mishu

Mishu007,

Do I need to change the account the app pool runs under from the default IUSR(anonymous) account to a domain user to be able to bind to active directory.  Or is there a way to impersonate the logged in user instead of changing the IUSR account?

Hi,

>> Can you debug the web service method? I mean does it enter in the method? Maybe it's an AD error.

Where should I place the breakpoint(s)?

>> I've noticed that in the web service the class name is ads and in the jQuery is ADS.asmx.

You are correct, I saw that to. I removed the ADS.asmx and ADS.cs files and recreated them with the code you supplied but I still get the same error poping up :(

>> Also write the correct path in the jquery definition of the web service file in order to work ok.

Not sure what you mean by that. I have it pointed to url: "ADS.asmx/GetADUsers", now. the index.aspx page is at root level and so is the ADS.asmx page. The code for ADS.asmx is stored in the App_Code directory.

Hi Mishu007,

Ok, I was able to get it to work. You were correct. I removed the .asmx and .cs and renamed the webservice with "ADS" and it worked fine. You had mentioned that and that was it. I'm going to repubish all markup/code that works.

The only minor thing that I noticed wrong is when I type a character such as "b" it starts the search for all "b's" but if I were to add "bri" during the search it does not recompile what I type it appears to finish the initial search for "b" and then I have to type in "bri" again. Is there a fix for that?

Also, is there a way to speed up the search?

Hi,

You can "trick" that minor problem by using a delay in the options for auto complete, also try setting the minLenght: 2 before the source argument this might also correct this issue.


As for the search to be quicker you can try to cache the results for the searches and use them when ever possible or try to restrict the AD query filter to be more specific. (Ex: limit the search only to a organizational unit inside the AD).

Thank you VERY MUCH for ALL your help for seeing this post all the way out. It means ALOT to me. This was something that I have never needed to do before and I can't thank you enough. Is there a reference that you use or used in helping me out with this? If so, could you post the link(s) to me?

Thanks again Mishu007.

Take care...

Hi,

I'm glad I was able to help you.

My links that I've used for reference are these:
This link is what I use when I need to query AD and of course msdn :).
AD in C#
I can't remember exactly which jQuery sites I've looked but I've used something from this one :Aspx jQuery autocomplete

Best of luck...
