BUG: https://bugzilla.samba.org/show_bug.cgi?id=15041
Only for environment ad_member_idmap_nss.
* !jacknompapper = \@jackthemappergroup
jackthemaper from group jackthemappergroup is mapped to jacknompapper
* !root = jacknomappergroup
since there is no '@' or '+' prefix, it is not an UNIX group mapping
