Can't get all groups a user is member of.. RRS feed

  • Question

  • Hi,

    I'm trying to get the user's groups in Active Directory.

    When passing user which is in Administrator group, it works fine.

    But when passing a regular user, I get a System.DirectoryServices.AccountManagement.PrincipalOperationException.

    whith the message:

    An error (1301) occurred while enumerating the groups.  The group's SID could not be resolved.

    public IEnumerable<string> GetGroupNames(string user, string domain)
                var pc = new PrincipalContext(ContextType.Domain, domain);
                var src = UserPrincipal.FindByIdentity(pc, user);
                var groups = src.GetAuthorizationGroups();
                var result = new List<string>();
                groups.ToList().ForEach(sr => result.Add(sr.SamAccountName));
                return result;

    Any Ideas?

  •  PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

                // find the group in question
                GroupPrincipal group = GroupPrincipal.FindByIdentity(ctx, "GroupName");

                // if found....
                if (group != null)
                                  // iterate over members
                    foreach (Principal p in group.GetMembers(true))
                        Console.WriteLine("{0}: {1}", p.StructuralObjectClass, p.DisplayName);

                        // do whatever you need to do to those members
                        UserPrincipal theUser = p as UserPrincipal;

                        if (theUser != null && (theUser is UserPrincipal))
                            using (StreamWriter sr = new StreamWriter(@"FileName", true))
                                sr.WriteLine(string.Format("FirstName ={0} , LastName = {1} , Email = {2}", theUser.GivenName, theUser.Surname, theUser.EmailAddress));
