Active Directory Adding user to Group, HRESULT: 0x80072014

[cpajoe2001]

I am not sure if this is the proper place to put this thread but I have run into a road block. I am writing a web app that will create groups in Active Directory then add users to those groups. I have it creating the groups just fine however when i go to add a user i get. The requested operation did not satisfy one or more constraints associated
with the class of the object. (Exception from HRESULT: 0x80072014) And I can not find any help on this error. i'll post the stack trace below. Here is my code I am hoping someone can find out why it is failing.

public string AddUser2Group(string groupName, string location, string userID)
 
{
DirectoryEntry AD = new DirectoryEntry("LDAP://DC=ad,DC=domainname,DC=com);
DirectorySearcher ADFind = new DirectorySearcher(AD);
DirectoryEntry group = AD.Children.Find("OU=" + location + ", OU=SelfServeGroups");
 
// Add a single user to a group;
ADFind.Filter = "(&(objectCategory=user)(cn=" + userID + "))";
SearchResult results = ADFind.FindOne();
 
//To add the user's distinguished name to the member property on the group object, use the Add method.
string DN = results.Properties["distinguishedName"][0].ToString();
group.Properties["member"].Add( DN );
 
//Commit the changes to the directory.
group.CommitChanges();
return userID;
}

When I run it in debug mode everything apears to be good DN is the full Distinguished name. Please help me

I believe that you need to use the group.invoke method - see 8. Add a user to a group in this article:
Active Directory and .NET

Thank you.

Sorry I have figured out the problem. I was sleeping last night when for some odd reason I was thinking about this project and it came to me i never said what group to add the user to. I am trying to add it to the OU that the group is in and not the group. Sorry for all of you who took a look at this but I have solved it. I guess working on code for the day and just looking at this made me just over look this small point.

Thank you very much for that link that is a very good walkthrough.
