auth: consistent handling of well-known alias as primary gid
When a local user has its primary group id mapped to a well-known
alias or a builtin group, smbd accepts logins of such a user, but
fails tree-connects to shares with a "force user" set to this user
with an error of NT_STATUS_INVALID_SID.
This fix causes the connect to succeed and the NT token to resemble
the token that would have been created in a login.

winbind: Don't crash on invalid idmap configs
We should not leave NULL in idmap_domains[]. This will lead to NULL
ptr deferences in idmap_find_domain().
