Amending this troubleshooting.

Unix extension has been added to the active directory, and the
uidNumber for each user have been added in order to match the previous
uid as discovered by winbind.

smb.conf was amended as follow:
        winbind use default domain = Yes
        winbind enum users = No
        winbind enum groups = No
        winbind nested groups = Yes
        winbind refresh tickets = Yes
        winbind offline logon = Yes
	winbind nss info = rfc2307
        allow trusted domains = No

        idmap uid = 1000-1999999
        idmap gid = 1000-1999999
        idmap backend = ad
        idmap config ALLORATECH : backend = ad
        idmap config ALLORATECH : range = 1000-999999
        idmap config ALLORATECH : schema_mode = rfc2307

Looking at the winbind_ad module, it seems to me that should the nss
info and schema mode be set to rfc2307 ; it should use the uidNumber
entry for determining the uid of the user.

However, winbind still assign the RID + 10000 for the user's uid...

Is there a way to tell winbind precisely which uid to use ? what am I missing?

Thanks
