ad57cac7db source4 samr: Tidy DBG_WARNING calls
Move the calls to GUID_buf_string and dom_sid_str_buf into the
coresponding DBG_WARNING call, instead of using an intermediate variable.
While this violates the coding guidelines, doing this makes the code less
cluttred and means the functions are only called if the debug message is
printed.

1bb2a1c6b3 auth: For NTLM and KDC authentication, log the authentication duration
This is not a general purpose profiling solution, but these JSON logs are already being
generated and stored, so this is worth adding.

Some administrators are very keen to know how long authentication
takes, particularly due to long replication transactions in other
processes.

This complements a similar patch set to log the transaction duration.

05e25a728c rpc/samr: Fix PSO support in SAMR password_change RPC
To get the SAMR password_lockout test passing, we now just need to query
the msDS-ResultantPSO attribute for the user in the SAMR code. The
common code will then determine that a PSO applies to the user, and use
the PSO's lockout settings.
