My organization is in the position of having to support full Windows ACLs on CIFS shares. We've been successfully utilizing Samba 3.5.10-125 and vfs_acl_tdb to accomplish that. However, the size of the resulting /var/lib/samba/state/file_ntacls.tdb[.unique-extension] file(s) has introduced some new problems for me to solve. In our environment, it seems on average each stored ACL causes file_ntacls.tdb to grow by almost 1000 bytes. That's what I've observed with my customers - YMMV. We have to support millions of files per server,...

...l place all extra file attributes (NT ACLs, DOS EAs, streams, etc), in that tdb. Note: This way it is not efficient and doesn't scale well. That's why it shouldn't be used in production! This seems to be very similar to "vfs objects = acl_xattr" (which uses /var/lib/samba/file_ntacls.tdb, so probably the same technology). Is it a problem to use "vfs objects = acl_tdb" in production? Or would it just cost a few percent performance? I have 4TB (8,168,443 files, took ~2hr to count) spinning storage, dimensioned for 20TB. I could assing a few more cores or a bit more RAM...
