Re: [Samba] wbinfo -i returns the same id for all users, authentication doesn't seem to go through winbind at all

I've added 

idmap config * : backend = tdb
idmap config * : range = 10000-30000

to smb.conf, and now 'wbinfo -i TESTDOMAIN\\user' returns correct ids.

I've found in the FAQ a mention of this, however it's obsolete:

I have set up a domain member using the idmap_ad backend, but getent
passwd and getent group does not show users or groups

If you want to show all users and groups, you will need to add these
lines to smb.conf:

   winbind enumerate users = yes
   winbind enumerate groups = yes

These options are not recognized by 'testparm'.
