Hello. Recently i setup backup server with heartbeat for my proxy. Squid setup is very simple, it uses pam_auth for user authorisation and http authentication. Works fine. Backup server is exact copy of primary ,except some system config files. Both systems are Debian 4.0/squid 2.6.5-6. Squid cache/logs are on DRBD disk. Squid on primary server works just fine - users successfully login and access internet. When i move resources to backup node, squid starts ok, listens for connection and users are prompted for password when they try to access internet. But proxy doesn`t allow them to do it - it keeps asking password. I don`t understand what`s going on: config is the same, binaries are the same, client restarted browser. Maybe there are some things i don`t understand about how squid authenticates users? Which logs should i watch and what should i see there to understand where the problem is? P.S. When i switch back to primary node - all works OK.
