Yes, thanks!  I don't understand that at all.  What is 'netlogon proxy only'

If winbind is mapping a sid to the uid/gid recorded in AD via the sfu
schema attributes, then why would I tell winbind what range it can use for
the uids and gids that it maps the sids to?

Also, what relationship do my idmap id ranges have to the actual values
in AD for the msSFU30UidNumber and msSFU30GidNumber attributes?  Do I
need to ensure that my idmap id ranges match the ranges of values used
in AD for msSFU30UidNumber and msSFU30GidNumber?

Thanks again!  This is good news.
Happy Landings,
