This changes our Unix primary GID behaviour back to what most people expect:
Samba will now use the user's UNIX primary group, as the primary group when
dealing with the filesystem. The NT primary group is ignored in unix.
For the NT_TOKEN, the primary group is the NT priamry group, and the unix
primary group is added to the NT_TOKEN as a supplementary group.
This should fix bug #109, but will need to be revisited when we get a full
NT group database.
Also in this commit:
- Fix debug statements in service.c
- Make idmap_ldap show if it's adding, or modifying an existing DN
- Make idmap_ldap show both the error message and error string
