pid formatted incorrectly in debug message (wrong printf format?)

["Norman Gray" <gray [at] nxg.name>]

Greetings.

When running nslcd in debug mode (`nslcd -d`), I see lines such as

    DEBUG: connection from pid=18446744073709551615 uid=0 gid=0

This is an implausible pid number.  This originates from a line

    log_log(LOG_DEBUG, "connection from pid=%lu uid=%lu gid=%lu",
          (unsigned long int)pid, (unsigned long int)uid, (unsigned 
long int)gid);

in nslcd.c (I'm looking at both the repo).

That pid number is -1 as a long unsigned.  Thus the problem here appears 
to be that getpeercred is failing to obtain the PID and either not 
reporting it or not detecting it.  (if so, that's also a problem).

This isn't merely cosmetic for me, since I'm running nslcd in debug mode 
to try to identify a process which is trying to communicate with nslcd.

I'm seeing this on FreeBSD 11.2, which is running v0.9.9.

Best wishes,

Norman
