Check Text ( C-35893r2_chk )
Check network services daemon files have no extended ACLs.

# ls -la /usr/sbin

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.

Note: Network daemons not residing in these directories must also be checked.
Fix Text (F-23542r1_fix)
Remove the extended ACL from the file.
# setfacl --remove-all /usr/sbin/*
