EP --> LDAP: "Peer certificate is not trusted or expired"



we are trying to connect our portal server (2004s) to the corporate LDAP-Server (Novell) via SSL in read only mode.

Unfortunately due to our IT infrastructure the portal server can't see the LDAP-server directly. There is a router inbetween the two which translates the IP-address and the port of the LDAP server.

We entered all information the way the portal server sees the LDAP server (including a valid dialogue user) and we can ping to the LDAP server from the UNIX-machine the portal is running on. Connection tests from the portal's UI fail.

The problem seems to be that the portal server rejects the certificate of the LDAP-server. We found "Peer certificate is not trusted or expired" messages in the defaultTrace files.

Am I right in assuming that the handshake is meant to go as follows:

1. First the LDAP server sends its certificate

2. The portal server authenticates it.

3. The portal server sends user name and password.

If that is the case, how can we make the portal server accept the certificate from the LDAP server even though the portal only sees the router? We already imported the certificate of the LDAP-server to the portal's key store, but the way I see it the problem is the router inbetween the two.

Unfortunately, getting rid of the router is not an option. 😉

Thanks a lot in advance,



The LDAP server logs contain the following:
