Hi all,

Is there any way that courier-imap can be configured to access more than
one LDAP server, so that if the primary server should fail, courier will 
failover to a secondary (or a tertiary)?

Unfortunately our LDAP servers are rather flaky (Netscape Directory
server 4.x - we're planning a move to OpenLDAP, but due to the number
of users in our database, it's a long way off at the moment), and they
tend to crash every so often (so much for support, sigh).

Whenever this happens, I have to restart the authdaemon, and the imap & pop 
servers, which is going to be rather annoying when this system goes live.

Actually, I suppose this is two problems ... if the LDAP crashes, why
doesn't courier recover when it comes back up again, and can I make it
failover to a second server?

I'm currently using version 1.4.3 (ie, the version supplied with Debian
Woody). Would any of the later releases solve either of these issues?

My authldaprc config, including irrelevent stuff, is:

LDAP_SERVER             ldap09
LDAP_PORT               389
LDAP_BASEDN             o=whatever.com
LDAP_BINDDN             uid=whoever
LDAP_BINDPW             whatever
LDAP_TIMEOUT            5
LDAP_MAIL               uid
LDAP_GLOB_UID           vmail
LDAP_GLOB_GID           vmail
LDAP_HOMEDIR            mailMessageStore
LDAP_MAILDIR            ./Maildir
LDAP_MAILDIRQUOTA       maildirQuota
LDAP_FULLNAME           cn
LDAP_CRYPTPW            userPassword
LDAP_DEREF              never
LDAP_TLS                0

Cheers,

Paul
