I use RT on several computers, and found that changes I made to RT-at-a-glance on one were not seen when I re-logged in on another. The browser is presenting the RT_SID cookie from a previous session, and RT then seems to use the cached RT-at-a-glance data perhaps from /opt/rt4/var/session_data.
Also if I logout of RT and log in again as a different user, the new user is authenticated correctly and gains the correct rights, but gets the (broken) RT-at-a-glance settings of the previous user. I am running RT 4.0.10 with mod_fcgid 2.3.6 and RT-Authen-ExternalAuth ldap authentication. -- RT training in Amsterdam, March 20-21: http://bestpractical.com/services/training.html Help improve RT by taking our user survey: https://www.surveymonkey.com/s/N23JW9T
