[Fedora-directory-users] Multiple masters and Round Robin DNS

[Ivan Ferreira]

Failover is done through the client configuration file, as you can define
multiple ldap servers.

How did you configured your Resource Records?

Try adding one for each hostname->ip, and another for DNS round robin. You
may have some problems with certificates if you use SSL.

After setting up 2 servers with multi-master replication, I added them both
to a DNS record so users will go to either server.

Both servers are replicating the NetscapeRoot DB to each other.  I made a
schema change to one and restarted it- only to see it hang.  I waited some
15minutes, and then discovered with netstat that it had a bunch of open
ldap connections to itself, which weren't timing out or going away.

After I removed the IP from DNS (disabled round robin dns) for the server I
was trying to shutdown , the server shutdown right away.

I'm guessing somewhere there's a configuration that needs to be pointed to
the other master server?

How are others doing load balancing/fail over ?
