I can reproduce this, and it appears to be related to label translations.

This is in the /etc/selinux/mls/setrans.conf file:

	# Secret level with compartments
	s2=Secret
	s2:c0=A
	s2:c1=B

Commenting out these entries makes login work again.

Failed login:

type=USER_ROLE_CHANGE msg=audit(1170092360.977:951): user pid=2498 uid=0 auid=4294967295 subj=system_u:system_r:sshd_t:s0-s15:c0.c1023 msg='sshd: default-context=staff_u:staff_r:staff_t:s0-s15:c0.c1023 selected-context=staff_u:staff_r:staff_t:Secret:A,B: exe="/usr/sbin/sshd" (hostname=?, addr=?, terminal=? res=failed)'

Successful login (translation commented out):

type=USER_ROLE_CHANGE msg=audit(1170092403.742:991): user pid=2553 uid=0 auid=4294967295 subj=system_u:system_r:sshd_t:s0-s15:c0.c1023 msg='sshd: default-context=staff_u:staff_r:staff_t:s0-s15:c0.c1023 selected-context=staff_u:staff_r:staff_t:s2:c0,c1: exe="/usr/sbin/sshd" (hostname=?, addr=?, terminal=? res=success)'

Is "Secret:A,B" correct syntax?
