Not really, wbinfo reads directly from AD, getent goes via nsswitch.

For getent to work using the 'ad' idmap backend, a few things have to 
fall into place:

You have to set the correct relevant lines in smb.conf.

You have have to give the Domain Users group a gidNUmber, or if using 
'idmap config WORKGROUP : unix_primary_group = yes', that the relevant 
group has a gidNumber.

You give the user a uidNumber and if using 'unix_primary_group' the 
relevant groups gidNumber

All Numbers used for the uidNumber & gidNumber attributes must be inside 
the range you set for the 'WORKGROUP' in smb.conf

Usually when a user doesn't get a UID, one of the above isn't correct.
