Answer 1

I experienced error code 1301 with UserPrincipal.GetAuthorizationGroups while using a brand new virtual development domain which contained 2 workstations and 50 users/groups (many of which are the built in ones). We were running Windows Server 2012 R2 Essentials with two Windows 8.1 Enterprise workstations joined to the domain.

I was able to recursively obtain a list of a user's group membership using the following code:

class ADGroupSearch
{
    List groupNames;

    public ADGroupSearch()
    {
        this.groupNames = new List();
    }

    public List GetGroups()
    {
        return this.groupNames;
    }

    public void AddGroupName(String groupName)
    {
        this.groupNames.Add(groupName);
    }

    public List GetListOfGroupsRecursively(String samAcctName)
    {
        PrincipalContext ctx = new PrincipalContext(ContextType.Domain, System.Environment.UserDomainName);
        Principal principal = Principal.FindByIdentity(ctx, IdentityType.SamAccountName, samAcctName);
        if (principal == null)
        {
            return GetGroups();
        }
        else
        {
            PrincipalSearchResult searchResults = principal.GetGroups();

            if (searchResults != null)
            {
                foreach (GroupPrincipal sr in searchResults)
                {
                    if (!this.groupNames.Contains(sr.Name))
                    {
                        AddGroupName(sr.Name);
                    }
                    Principal p = Principal.FindByIdentity(ctx, IdentityType.SamAccountName, sr.SamAccountName);

                    try
                    {
                        GetMembersForGroup(p);
                    }
                    catch (Exception ex)
                    {
                        //ignore errors and continue
                    }
                }

            }
            return GetGroups();
        }

    }



    private void GetMembersForGroup(Principal group)
    {
        if (group != null && typeof(GroupPrincipal) == group.GetType())
        {
            GetListOfGroupsRecursively(group.SamAccountName);
        } 
    }

    private bool IsGroup(Principal principal)
    {
        return principal.StructuralObjectClass.ToLower().Equals("group");
    }
}
