Question:

When there are multiple certificate chains on a Keyring how can you determine which certificate chain is being used?

Answer:

Top Secret can trace the calls and the keyring being read but we do not have a trace that shows the certificate and the chain that is being used.  IBM does have an SSL trace that will show the connection being established between point A and point B and which certificates(s) are involved.  Contact IBM for the commands and SSL trace information.
