Hello Wesley,

And that's all? At a minimum, if authN is failing, you should get
this syslog:
if ((r = backend_authenticate(ret, prot,&mlist, userid,
cb, auth_status))) {
syslog(LOG_ERR, "couldn't authenticate to backend
server: %s",
sasl_errstring(r, NULL, NULL));
if (!ret_backend) free(ret);
close(sock);
ret = NULL;
}
If you're not, I guess you're in some sort of loop in
backend_authenticate(). Do you get a backtrace?
I'm new to gdb, so I hope I don't give you any wrong information.
I set a breakpoint on backend_authenticate but i don't get any break.
However I set a breakpoint in backend_connect and stepped a lot.
Please see attached file "bt" and bt2.
I could not get a good backtrace because I didn't know how to get it.
However the file bt2 shows the backtrace I was able to get. I don't
know how to say break on a specific line. as the line numbers gdb shows
are not matching the line numbers in the source file :(.
Thank you very much!
Rudy
