> Thanks Rowland, I wasn't aware of RFC2307 and found idmap_ad which may just do what I need. I just need to come up with a plan for populating uidNumber and gidNumber in AD in a way that makes sense and has no room for human error. Looked into vfs_fruit, bit confused about how it would help but will keep researching.
If you weren't aware of the rfc2307 attributes, then you probably also
aren't aware of the msSFU30MaxUidNumber & msSFU30MaxGidNumber attributes
that should be in:
Where 'samdom' is your lowercase workgroup name and
'DC=samdom,DC=example,DC=com' is your AD rootdse
These two attributes are where windows stores the next uidNumber &
gidNumber, both usually start at 10000
