[Samba] allocate_print_jobid: failed to allocate a print job for queue lbrmgt

[Mineau, Kevin]

Update / resolution:

After additional investigation into our problem, we have occasionally
seen an entry like:

   wks069195 (<ipaddress>) connect to service lbrmgt initially as user
nobody (uid=-2, gid=-2) (pid 1015860)

We then opened up the permissions on /var/spool/samba/lbrmgt.  (chmod
777)
Since then this error condition has stopped.
