# id hacluster
uid=17(hacluster) gid=60(haclient) groups=60(haclient)
# ps -u hacluster
  PID TTY          TIME CMD
 2335 ?        00:00:00 cib
 2339 ?        00:00:00 attrd
 2340 ?        00:00:00 pengine
 2355 ?        00:00:00 crmd
# grep -E '^(Uid|Gid|Groups)' /proc/2355/status
Uid:	17	17	17	17
Gid:	0	0	0	0
Groups:	

So, crmd runs with the 'hacluster' uid, but no associated gid/groups.
Can this be the problem?
