Hallo Experts,

I am using Active Directory. I need to get output of

whoami /FQDN

command in C#. I can get user informations from

System.Security.Principal.WindowsIdentity wi = System.Security.Principal.WindowsIdentity.GetCurrent();

But I want to get the OU also what is given by whoami /FQDN.

Please help

Regards,

Soumen

Try:
var sid = System.Security.Principal.WindowsIdentity.GetCurrent().User;
var user = new System.DirectoryServices.DirectoryEntry(string.Format("LDAP://<SID={0}>", sid.Value));
var cn = user.Properties["distinguishedName"].Value;

Console.WriteLine(cn);

Try having a play with the following code:

        DirectoryEntry searchroot = new DirectoryEntry("LDAP://dc=yourdomainname,dc=com");
        DirectorySearcher ds = new DirectorySearcher(searchroot);
        ds.SearchScope = SearchScope.Subtree;
        ds.Filter = "(&(objectclass=user)(samaccountname="+ wi.Name +"))";
        SearchResultCollection searchResults = ds.FindAll();
        string UserDetails = searchResults [0].GetDirectoryEntry().Properties["distinguishedname"].Value

Open in new window


Using the code above you should be able to get to all the information you require, you may need to change which property you return the value of 'distinguisgedname' gets various info which may be useful to you but there are lots of other properties.

The other thing you may need to look at is passing the windows identity name to the samaccountname filter, you may need to only pass the username and not the domain (i.e 'username' not 'domain\username').

so like I said you will have to play around with it but it should give you what you need.

wdosanjos post wasn't there when I started typing! his solution seems much easier to follow.

Mine was a cut down version of what I use for a address book search facility so probably overkill for what you need.
