Hi,
I need to get all the objectClass which are = user
and the OU match a variant i compare to.
I wrote:
search.Filter = "(&(objectClass=user)(OU=_VAR))";
but the search result get nothing. (_VAR is a variant in which i pass a string).
What is the right syntax??
Thanks

Hi,
Thanks for the reply.
I forgot to mention - C#,
OK, i wrote -
search.Filter = "(&(objectClass=user)(OU=" + _VAR+ "))";
but i get nothing.
If i put the filter in the LDAP it's OK  -
      DirectoryEntry root = new DirectoryEntry("LDAP://10.1.1.1/OU=" + _VAR + ",DC=Internet,DC=Ladpc",
             "User", "Pass", AuthenticationTypes.ServerBind);

            DirectorySearcher search = new DirectorySearcher(root);
            search.Filter = "(&(objectClass=user))";

Any Idea?

Im not sure you can filter on ou the way you are trying to...

but as you said if you add the ou in to the adspath then its working so you can just use that

My problem is that i need to move the LDAP path to the app.config.
i wrote (at the app.config) :
<activeDirectorySettings defaultServer="Test">
    <servers>
      <clear />
      <add host="10.1.1.1" namingContext="DC=Internet,DC=Ladpc" userName="User" password="Password" name="Test" AuthenticationTypes="ServerBind" />
        </servers>
  </activeDirectorySettings>

And my problem is that i don't know how to pass a variant (_VAR) to the app.config.
If i will succeed doing it in this way, it will solve my problem!!
Can you help with that?   (I mean - pass a variant to app.config - if it is possible)
Thanks

so what does your code snippet look like when it is using the app.config file?

search.Filter = String.Format("(&(objectClass=user)(dn=*OU={0}*))", _VAR);

This should work, since the OU should be a part of the DN of the object. Remember to set the search scope to Subtree.

Rytmis, sorry i steel get nothing.
Colosseo - it looks like that -
        public static string ADconnectionString = ConfigurationManager.AppSettings["Test"];
        DirectoryEntry root = new DirectoryEntry(DataComm.ADconnectionString);

Rytmis could be on to the solution you need

try adspath instead of dn:

search.Filter = String.Format("(&(objectClass=user)(adspath=*OU={0}*))", _VAR);

Sorry guys it just dosn't retrieve anything, (  Thanks for the effort  (:    )
my code is :
--------------------------------------------------------------
            public static string ADconnectionString = ConfigurationManager.AppSettings["Test"];
            DirectoryEntry root = new DirectoryEntry(DataComm.ADconnectionString);
            DirectorySearcher search = new DirectorySearcher(root);
            search.SearchScope = SearchScope.Subtree;
            search.Filter = String.Format("(&(objectClass=user)(ADsPath=*OU={0}*))", _VAR);

            search.PropertiesToLoad.Add("Name");
            search.PropertiesToLoad.Add("ID");

            SearchResult result;
            SearchResultCollection resultCol = search.FindAll();
           
           string[] allUsers = new string[resultCol.Count];
            string[] allID = new string[resultCol.Count];

            if (resultCol != null)
            {
                for(int counter=0; counter < resultCol.Count; counter++)
------------------------------------------------------------------------------------- and so on....
Count allways  = 0 !! , but again, if i put the " OU=_VAR " at the LDAP it's OK.
What else can i do???

The other option is to put the placeholder in your namingContext attribute in the app configuration:
<add host="10.1.1.1" namingContext="OU={0},DC=Internet,DC=Ladpc" userName="User" password="Password" name="Test" AuthenticationTypes="ServerBind" />

and then:

string adConnectionString = String.Format(ConfigurationManager.AppSettings["Test"], _VAR);

(I'm assuming that AppSettings["Test"] returns the connection string as a concatenated string composed from attributes of the app.config element)

This is not the prettiest solution, but it should work. :)
