Chasing through the code it looks like getgrnam_r() fails in

Scratch that, restarting slurmctld doesn't provoke the "error: Could
not find configured group vlsci" any more, but members of that group
can still not submit to that partition:

Hi Chris,
We're successfully using AllowGroups with 2.6.0 for a number of
partitions. One cluster is running Scientific Linux 6.3 and SLURM 2.6.0,
another is running 6.4 and SLURM 2.6.0pre4.
These are two AllowGroups snags we've run into:
Unlike nscd, sssd doesn't allow enumeration by default (and is
case-sensitive). We add this to /etc/sssd/sssd.conf on the slurmctld
node:
enumerate = True
case_sensitive = False
If you have large groups, you might run into the buffer size limit,
which is 65k characters. (PW_BUF_SIZE in uid.h)
Since it's working on one cluster, I'd suspect sssd.
Regards,
John
