Version 5.0 brought a new feature to the Accounts tab showing Last Login Time. (At least I think it was new in 5.0). Unfortunately this information does not seem to be accurate. I had noticed it a few weeks ago when investigating an issue with a user. Admin console showed the user hadn't logged into Zimbra for about a week. When I questioned the user he said he logged in and out every day. Didn't get a chance to look into it any further then, but I had reason to check it again for another user this morning and again it proved not to be correct. I verified with my own account. I logged out and back in to Zimbra, but the "Last Login Time" did not seem to be updated.
I'm thinking this might be related to the "Auth Token Lifetime" setting, but I'm not sure. I currently have this set to 2 days for everyone. So, am I right in thinking I need to change this setting, and if so what would I need to set it at to get more accurate info in the Admin Console? Or is this just a bug? I did Bugzilla and the forums before posting this and came up empty. Hopefully I didn't miss anything.
