SubAdmin login session error

PROBLEM
I keep getting a session error when trying to login as a SubAdmin.

ENVIRONMENT

• On-Premise Server + WebMail Installations: Version 6.0 > Current Version
• Webmail Only Installations: Version 6.0 > Current Version

CAUSE
/var/lib/php/session must be owned by the WebServer user.

RESOLUTION

1. If you are experiencing problems with logging into SubAdmin due to session error try the following.
   

   cat /etc/php.ini | grep session

2. Find:
   

   session.save_path = "/var/lib/php/session"

3. This directory must be owned by the webserver user.
4. To find the webserver username.
   

   ps aux |grep httpd

5. Change directory owner.
   

   chown -R atmail:atmail /var/lib/php/session
