I am running Fedora 9 with the MLS policy and see no evidence that the label translation is enabled. I am using the default setrans.conf and the "disable=1" flag is commented out.

Using the selinux_trans_to_raw (e.g., with a SystemHigh level) produces the exact same label string as passed in which will not pass validation (using s15:c0.c1023 will pass validation).

Trying id-Z followed by newrole produces:
id -Z
warner_u:secadm_r:secadm_t:s0-s15:c0.c1023

newrole -l SystemLow-SystemHigh
warner_u:secadm_r:secadm_t:SystemLow-SystemHigh is not a valid context

Is there something that must be done to activate label translation?

thanks

Andy
