I've never seen it work adequately with RHEL 3 & 4 or Solaris 8 clients (solaris 9 seems to work fine). We use Piranha (which also distributes the load nicely) to get around it.

Hi all
We are currently using Sun's Directory server and have had some problems with clients failing over to the other master if one fails. The clients are a minxute of RHEL 3 WS and Solaris 8 (SPARC), and the Sun Directory servers are both Solars 9 (SPARC) running Directory One 5.1.

We're using the bog standard nscd daemons provided by the OS vendors. We also use IDSync to synchronise user passwords from AD to LDAP but not from LDAP to AD.
What we're finding is if ldap1 dies for some reason, the clients don't failover to ldap2.
We don't know if the problem is client side or server side. Would Fedora Directory Server, set up in a similar manner, also not failover properly? While we're prepared to look at Fed DS, there is a feeling that it too will behave in the same manner, given they are both forks of the same project.
Comments?
Thanks
