Details
Check Text (C-216310r959010_chk)
If X Display Manager (XDM) is not used on the system, this is not applicable.
Determine if XDM is running.
Procedure:
# ps -ef | grep xdm
Check the file permissions for the .Xauthority files.
# ls -lL .Xauthority
If the permissions include a "+", the file has an extended ACL and this is a finding.
Fix Text (F-17544r371019_fix)
Remove the extended ACL from the file.
# chmod A- .Xauthority
