yes, I use backend = ad , if configure backend = ad with realm [1] (as
you said is wrong ) every 'getent passwd username' give me a new
uidNumber or make a new uidNumber in sequence [1].
when I  configure backend = ad with workgroup (as you said that must
have to be ) 'getent passwd username' don't produce any new id .
and in /var/log/samba/winbindd.log I see 
Could not convert sid S-1-5-21-2685600491-4108878147-961307473-2662:

idmap config CORP.LOCAL : backend = ad

root at repo:~# getent passwd "vmjp01"
root at repo:~# getent passwd "maa001"
root at repo:~# getent passwd "tsdg01"
root at repo:~# getent passwd "rmac01"
