[389-users] openldap client HA for multimaster replication

[Ryan Palamara]

Sorry,

If I just stop the dirsrv service on the first server, the ldap clients authenticate against the second server instantly.

However if the first server is shutdown, then it take 10-15 seconds for clients to failover authentication to the second server.

Thank you,

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?

Can you explain exactly what you mean by "stops working" and "down completely"?  I'm not sure why that would make a difference.
