Any idea what Dovecot version? rhel4 had 1.0.rc15 I think? I know there were some LDAP bugs in it, but I don't really remember anymore. Did Dovecot really try to access the server2, or was it simply unable to reconnect to the LDAP server at all? If the latter, it's probably just rc15 bug.
Since the customer has been using RHEL4.3, Dovecot version should be something in between dovecot-0.99.11-2.EL4.1 and 0.99.11-9.EL4. These are all for RHEL4. I'm sorry that I have not been provided the version.
Like Charles said, from my point of view v0.99 is dead and buried. It's simply too old version to waste any time on its bugs.
- About the specification of dovecot for reconnection
In case Dovecot switch to server2 due to server1 gets some problems such as service down, does the server2 never reconnect to the server1 even the server1 become available to respond again? Even if so, is it sure that if the server2 is down, then does Dovecot normally try to connect to the server1?
All of this is handled by OpenLDAP library internally and I don't know how it works. But my GUESS is that it always simply connects to the first working server and never disconnects from it by itself.
- Configuration by 'hosts' and 'uris' parameter in dovecot-ldap.conf
Is there any differences for the way to reconnectionś behavior between those parameter? I believe that both parameter can specify sevral ldap server, then I would like to know whether each parameter does the action for reconnection in the same way.
Again this is handled by OpenLDAP internally. And again my GUESS is that there's no difference between their reconnection handling.
