Hi, I've got a strange problem with FR 2.1.12, sometimes (not always) when logrotate ran, freeradius goes bonkers and responds to every pap request with "mschap xlat failed". Restarting FR fixes this magically and all works fine again. I created a small and hackish script, which restarts FR when this happens. The output showed that about every second week (logrotate runs weekly) this happens. Because FR works fine again after a restart, restarting FR in debug mode is not an option to get more information. But here is a snipped from my radiusd.log showing the symptom: Sun Apr 8 06:49:50 2012 : Info: HUP - loading modules Sun Apr 8 06:49:50 2012 : Info: Module: Reloaded module "attr_filter.access_reject" Sun Apr 8 06:49:50 2012 : Info: Module: Reloaded module "mschap" Sun Apr 8 06:49:50 2012 : Info: Module: Reloaded module "radutmp" Sun Apr 8 06:49:50 2012 : Info: Module: Reloaded module "macs" Sun Apr 8 06:49:50 2012 : Info: Module: Reloaded module "pap" Sun Apr 8 06:49:50 2012 : Info: Loaded virtual server <default> Sun Apr 8 06:49:50 2012 : Info: Loaded virtual server inner-tunnel-ldap Sun Apr 8 06:50:01 2012 : Auth: Login incorrect (rlm_pap: mschap xlat failed): [someuser] (from client watchdog port 0) Sun Apr 8 06:50:02 2012 : Info: Signalled to terminate Sun Apr 8 06:50:02 2012 : Info: Exiting normally.

Sun Apr 8 06:55:01 2012 : Auth: Login OK: [someuser] (from client watchdog port 0) So my script ran radtest with the "someuser" credentials (which should always work), which failed, it then restarted FR and all worked fine again... Is there any more information I can provide? all the best, Jan
