No. We only add the gid to the groups we use at (human) user level. e.g.
Domain Users has a gidNumber and the group staff2 which we created

With the config as the OP has it, winbind will not assign any sensible

The reason is that windows uses SIDs for user and group management. It
has no interest in gid or uid numbers.

gidNumber in the directory then your configuration will never work.
