Active Directory (ADSI) C# Group Info LDAP Problem

ro · June 23rd, 2004, 01:43 PM

I have written a Web Based Login Module in C# that authenticates against my local PDC. As far as the authentication goes, it works great. The problem comes when I try to get all the groups the user logging in belongs to. And whatâs even WEIRDER is that it works fine when I run it from the development box (which is where the program resides and runs) but when I run (access it) it from another computer it will NOT get the group membership! Hereâs the code I use (Keep in mind the strUser has already been authenticated against the AD):

Code:

string getGroups (string strUser){
        DirectoryEntry obEntry = new DirectoryEntry(
          "LDAP://DC=courthousedata,DC=com");

        DirectorySearcher srch = new DirectorySearcher(obEntry, 
          "(sAMAccountName=" + strUser + ")");

        SearchResult res = srch.FindOne();

        if (null != res){
          DirectoryEntry obUser = new DirectoryEntry(res.Path);
           object obGroups = obUser.Invoke("Groups");
          foreach (object ob in (IEnumerable)obGroups){
            DirectoryEntry obGpEntry = new DirectoryEntry(ob);
            groupNames.Append(obGpEntry.Name);
            groupNames.Append("|");
          }
        }

      return groupNames.ToString();
}

In IIS I have setup a user that has the ability to read the AD. (Again this works from the local machine, even if in the local machine I change from http://localhost to http://nameofbox it still works)

Any Help is appreciated!
