Yes, there is a big difference (I tried to explain to you during CIFS
conf ;) :
When in security = ads, when we reply in reply_spnego_kerberos(), we build
a quite broken NT user token, one that has a local sid with an algorithmic
rid part (instead of using the user's original domain sid). Thus,
privileges never apply when smbd is running as a domain-member in
The best way to fix that (IMHO) is to derive (at least) the user and
primary-group sid directly from the PAC (saving roundtrips). I have
exactly this working (including PAC server-signature verification) for
Heimdal (thanks to the great Samba4 progress) but the abstraction-layer to
make it work with MIT kerberos as well is not yet finished.
You are right, I should open a bug report to track my progress on that.
