[Samba] UID/GID Issues with Samba in ADS mode with Winbind

[Dracula]

Hello

I am  seeing an issue where Winbind is not keeping it's UID/GID
mappings.  For how long does the mapping stay in effect?  Is this
mapping effected by reboots or server restarts?  Will an AD user get the
same UID/GID every time?  Is there a way we can ensure that the UID/GIDs
stick between login/logouts, etc. 

Thanks
