I am using a mix of CentOS 5 and 6 servers using openldap for
client ldap.
I have 2 289 Directory servers that are using multi-master replication.
When dirsrv stops working on the first server listed under URI,
authentication picks up seamlessly on the second LDAP server listed.
However if the first server is down completely, it then takes a long time
for authentication for go to the second server.
Any suggestions on what can be done with openldap, to allow the seamless
failover to the second server when the first one is down completely?
Depending on how expensive this slow authentication is, you could do anything from a
shared IP via haproxy to buy a BigIP pair from F5 and have your load balancer check that
the backend ldap daemons are up. Then the frontend will stop using a non-functioning
backend for ldap.
Thank you,
