Hi,

I am trying to determine of which groups a particular user is a member.  I 
am using the following code:

DirectorySearcher search = new DirectorySearcher();
search.Filter = String.Format("(SAMAccountName={0})", userName);
search.PropertiesToLoad.Add("memberOf"); 
SearchResult result = search.FindOne();

I get no errors for any user I try. The problem is certain users have the 
"memberOf" property and others don't.  However, when I look in AD, every user 
I try has groups listed in the "Member Of" tab of the properties of that 
user. 

Any ideas why "memberOf" property would come through for some users and not 
others? 

Is there a setting in AD that might be causing the issue?

Thanks in advance,

-Pete

I found the problem.  It was a security setting for particular users who 
where created after we switched domains.  Authenticated Users did not have 
read permission on certain accounts.
