Need help with SELinux and SGE/ssh

[Orion Poplawski]

I'm running Sun Grid Engine on a CentOS 5 cluster and am having trouble 
with SELinux preventing the proper setup of parallel environments. 
Turning SELinux off allows everything to work properly.

The problem seems to be when SGE tries to use ssh to login to a remote 
machine.  As part of this process, it starts up a private sshd daemon to 
handle the connection.  The relevant error appears to be:

type=USER_LOGIN msg=audit(1186001097.981:19489): user pid=12066 uid=0 
auid=0 subj=root:system_r:unconfined_t:s0-s0:c0.c1023 msg='acct=steph: 
exe="/usr/sbin/sshd" (hostname=?, addr=192.168.0.120, terminal=sshd 
res=failed)'
type=USER_ROLE_CHANGE msg=audit(1186001098.201:19491): user pid=12066 
uid=0 auid=0 subj=root:system_r:unconfined_t:s0-s0:c0.c1023 msg='sshd: 
default-context=user_u:system_r:unconfined_t:s0 
selected-context=user_u:system_r:unconfined_t:s0-s0:c0.c1023: 
exe="/usr/sbin/sshd" (hostname=?, addr=?, terminal=? res=failed)'

sshd reports:
Aug  1 14:44:58 coop00 sshd[12066]: error: deny MLS level 
SystemLow-SystemHigh (user range s0). Continuing in permissive mode

I'm at a loss here.  Can anyone explain what is going on and what is 
failing?  How can I make it work without running in permissive mode?

Thanks!
