GetAuthorizationGroups returns more groups than my

问题:

i found this post to get the security groups of a user.

I had to change it a bit so it looks like this:

public List<GroupPrincipal> GetGroups(string userName, string userPassword, string userDomain)
    {
        List<GroupPrincipal> result = new List<GroupPrincipal>();

        // establish domain context
        PrincipalContext yourDomain = new PrincipalContext(ContextType.Domain, userDomain, userName, userPassword);

        // find your user
        UserPrincipal user = UserPrincipal.FindByIdentity(yourDomain, IdentityType.SamAccountName, userName);

        // if found - grab its groups
        if (user != null)
        {
            PrincipalSearchResult<Principal> groups = user.GetAuthorizationGroups();

            // iterate over all groups
            foreach (Principal p in groups)
            {
                // make sure to add only group principals
                if (p is GroupPrincipal)
                {
                    result.Add((GroupPrincipal)p);
                }
            }
        }

        return result;
    }

Unfortunately I now get every security group in the AD and not only the ones the user is in. My user is in 10 groups but it returns 71. I had to submit username and password or else I would not be allowed to look up the groups. It is an administrative account on a different domain so I couldn't use the current credentials.

If you need more info please let me know.

Greetings and thanks in advance IG

Is there a chance that the 10 groups are members of other groups? According to the documentation:

UserPrincipal.GetAuthorizationGroups Method

This method searches all groups recursively and returns the groups in which the user is a member. The returned set may also include additional groups that system would consider the user a member of for authorization purposes.
