Description
Hi again,
i'v read a lot of topics here on forge or mailing lists about users beeing logout from backend. I have never before expirienced this problem till the last month.
I moved my project to productive account (it is on the same server as my dev account - shared hosting - so the environment was the same). The only difference was switch to official domain (and probably some core updates as i'm using latest git version there). Then my backend starts to freak. I couldn't do languages updeate as after 5-6 items were checked there was an error and i had to login again. After some operation like upload images, or copy/paste some content elements the same problem. Even when i left backend for a minute inactive (i was doing something in other app) i get logout. It was annoying as i was kicked of the backend during some operation, like i mentioned before: files upload, contend edit/save, languages update etc.
I had this problem wih 6.1.x but few days ago i have started next project using 6.2-dev and i the same started.
I doubt the issue is inet provider as i can confirm it happens on 3 different machines (my laptop + friends network, my pc + home network, pc at work + work network) with 3 different networks.
All configurations related to session, cookies were default.
Yesterday i have changed from 4 to 0 this one:
[BE][lockIP]= 0
and the problem with beeing logout seems to be gone (on T3 6.2). I have tested this a bit more on 6.1 and values > 1 for this parameter cause the logout problem. Setting it to 0 or 1 'resolves' my problem.
So now im curious if there is some problem in T3 Core because i can't figure out what can cause this issue on my/server side.
TYPO3 6.1 and 6.2
PHP 5.5
Server Apache + Varnish (is turned off for typo3/ directories)
