I understand and I am not trying to induce any problems/hard feelings. I understand a lot of work has gone into SAMBA.
However, if we start using winbind, will not our existing UID and GIDs set withing our existing backend will be useless?
Meaning, *ALL* of our production servers have files and directories based off of these static UID and GID numbers assigned within our
OpenLDAP backend. I may be wrong here but If we introduce winbind, the UID and GID numbers will be changed based off of winbind
using the SID and multiplying, etc., to get a new UID/GID value that is not even close to our existing production environment. No groups
or users would be recognized on folders and files due to incorrect UID/GID numbers. I am talking about a lot of production file servers here.
So, is there a way/configuration setting to prevent winbind from taking existing, *statically set*, UID/GID numbers on our users and groups
and applying the SID multiplication to come up with a new UID/GID numbers for these existing POSIX users and groups?
If not, woe is me.
