Hi people, I have a setup configured using ldap, I have noticed that after a period of user inactivity if a client open connections to dovecot first attemps fails with this:
Nov 16 19:34:43 cl05-02 dovecot: auth: Error: ldap(user@xxx.xx.xx,172.29.13.26): Connection appears to be hanging, reconnecting
After the connections to ldap has been restablished everything starts working ok, is this a expected behavior or I'm missing something??
You have a firewall or something that drops the connection after it has been idling for a while. And when Dovecot continues trying to send another LDAP request, it simply drops the packets instead of even bothering to reject them. Not good.
