Get the list of Groups for the given UserPrincipal

I want to get the list of groups which the user is in.

This is my code:

PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "mydomain.ac.uk",   "DC=mydomain,DC=AC,DC=UK", "user", "password");

UserPrincipal user = UserPrincipal.FindByIdentity(ctx, IdentityType.SamAccountName, "MyUser");

PrincipalSearchResult<Principal> results = user.GetGroups();

foreach(Principal p in results)
{
   Response.Write(p.Name);
}

When I run, I got the following error at the line Response.Write(p.Name);

System.Runtime.InteropServices.COMException: The specified directory service attribute or value does not exist.

When I checked the count of the results, it returned 9 and the first group is DomainUsers.

How can I iterate all 9 groups in the list? Thanks.

The following is the list of users I get:

try something like 

foreach(Principal p in results)
{ 
   if (p is GroupPrincipal) 
      Response.Write(p.DisplayName); 
}

I know it sounds dumb, but it has worked for me in the past. Your results look like it only actually found 1 security group and 8 "other" types of groups. Those "other" groups may not possess those attributes.
