Details

Check Text ( C-35968r1_chk )
Verify NIS/NIS+/yp files have no extended ACLs.
# ls -lL /var/yp/*
If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text (F-23574r1_fix)
Remove the extended ACL from the file.
# setfacl --remove-all /var/yp/*
