JNDI, SSL, and Websphere problem on AS/400

[Seth <sethmreagan@xxxxxxxxx>]

I am using JNDI to connect to a Sun One Directory Server from
Websphere. It works fine when running Websphere on our developer
(windows-based) workstations but when we put it on the 400 it gets
into an (seemingly) infinite loop. We looked at the network traffic
through a sniffer and it just keeps repeating itself even after an ssl
ALERT (Level: Fatal, Description: Certificate Unkown) pops up.

The message that keeps repeating complains about an incorrect checksum...

We have verified that:
1.) we are using the 1.3 jvm.
2.) the certificate is imported into the cacerts file of said jvm.
3.) both environments (workstation and server) are using the
com.ibm.jsse.IBMJSSEProvider

Can anyone help? 

Here is the beginning of one of the logs which proves a couple of the
assertions that I have made:
