openldap and heimdal persistent connection

Hello,

We're currently running openldap 2.2.20 with the back-hdb ldap backend. It's being used as a proxy to forward ldapi queries from heimdal 0.6.3's ldap backend to a Sun Directory Server 5.2 which doesn't natively support ldapi.

It seems that the connection is persistent such that restarting the Sun Directory Server requires us to then restart openldap in order to make heimdal work properly again.

Is there any way around this so that openldap doesn't require restarting each time someone restarts the Sun dierctory?

Thanks for any info.
