Description of problem:

User is having difficulty in getting the auto-logout instructions to work. They are attempting to follow the instructions from here:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Desktop_Migration_and_Administration_Guide/user-sessions.html

A description of their attempts is found on the Scientific Linux User mailing list: 

http://listserv.fnal.gov/scripts/wa.exe?A2=ind1506&L=scientific-linux-users&T=0&P=6815

Version-Release number of selected component (if applicable):

7.1

How reproducible:

The instructions appear to work for shorter timeouts, but the user thinks that the screensaver kicking-in may disrupt longer timout settings. I don't think that this affects me on Fedora 22 (I tried a 15 minute log-out setting, and my screensaver kicked-in during that timeframe), but it may be different between EL7 and current Fedora. Also, the current docs from git include slightly different instructions at the start of the help steps.

Steps to Reproduce:
1. Follow instructions as noted in EL7 documentation, but set timeout for 3 hours  (I will verify the exact duration with the person who is having the issue).
2. Allow computer to idle for that length of time.
3. See if system automatically logs out.

Actual results:

System logs out for shorter durations, but not when the setting is set to longer durations (i.e., several hours).

Expected results:

System should log out at appropriate time, whether the setting is set to a short duration or a longer duration.

Additional info:

Should also test to see whether docs in git master can be applied to current EL7 documentation.
