dovecot - Apr 2012 - ldap idle connection timeout in DoveCot 1.0.13?

Hi there,

We are using DoveCot 1.0.13, it connects to LDAP server for authentication. It
seems that DoveCot keeps the idle LDAP connection open.

Our firewall is terminating these connections after some time of idle activity
(2 hours), then, we run into authentication problem. If we restart either LDAP
or DoveCot, then it is fine.

Can we set some kind of LDAP idle connection timeout in DoveCot? 
/etc/dovecot-ldap.conf.  I do not see any configuration available for 1.0.13.

Another alternative is to set idle connection timeout in LDAP, but we prefer
doing that in DoveCot.

Thanks,
Yan

Yes.

No. But if you upgrade to a newer Dovecot (v2.x probably) this is solved by
automatic transparent reconnection.
