Description of problem: When using "ssh user/role/level@host" to log in at a specified level, this fails when using level "s2:c0,c1". It works for "s3:c0,c1" and other levels. The problem appears to be the translations done by mcstransd. 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 audit log: 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?
