Glad to hear.

Indeed, Windows FSRVP clients require Kerberos authentication, so AD
domain membership is needed. That said, the prototype Samba asynchronous
RPC server implementation introduces a bug in the winbindd_dual_ndrcmd
code path, which causes a panic on AD user lookup. I don't yet have a
suitable fix for this issue.

IMO there are still a few things blocking upstream inclusion, aside
from the aforementioned bug:
1. FSRVP server state machine timeouts (started)
2. Automated FSRVP testing as part of selftest (started)
3. Thorough testing of the asynchronous RPC server changes
4. Code review

I plan to address points (1), (2) and the async RPC server bug in time
for SambaXP in May.

Cheers, David
