What I'd like to do, is put some instrumentation in place that would allow our monitoring server to fire ntlm_auth's at a specified domain controller (rather than whichever one winbind happens to have connected to) so that we can monitor latency to all of them, and use the resulting graphs to pinpoint any that are under performing.
I can't see an obvious way to make that happen, so if anyone has any pointers we'd really appreciate it!
You might be able to find which DC is being used, and an indicative latency, by writing a small program to call wbcPingDc2 and note the time taken to respond and which DC was used. Log this
Except here I get # ./dclatency error: unable to ping dc WBC_ERR_NOT_IMPLEMENTED # :( Look through wbclient.h. There may be another way.
