Details

Check Text ( C-36357r3_chk )
Verify /etc/shadow has no extended ACL.
# ls -lL /etc/shadow

If the permissions include a "+", the file has an extended ACL, this is a finding.

If the /etc/shadow file does not exist and the system is in Trusted Mode, this is not a finding. To verify Trusted Mode:
# ls -lLR /tcb/files/auth/[a-z,A-Z]*

The TCB file(s) should exist and must not have extended ACLs.
Fix Text (F-31693r2_fix)
Switch the system to Trusted Mode via:
# tsconvert

Or alternatively, HP-SMH, the SAM replacement may be used to perform the same task.
