IT05322: TCPIP CLIENT NODES FAIL 2-WAY SSL HANDSHAKE

APAR status

• Closed as program error.

Error description

• When TCPIP Client nodes are used to connect to a server that is
  configured for ssl client authentication, it is seen that broker
  fails to send its certificate (client certificate) for the
  server to verify as part of SSL handshake. The issue happens
  when the
  server sends an empty list of CA's with the "CertificateRequest"
  handshake message.

  PROBLEM DESCRIPTION:
  If a remote server returns an empty list of Certificate
  Authorities (CAs) when the TCPIP Client nodes are used to
  connect to a server that is configured for SSL client
  authentication, then the broker fails to send its client
  certificate to the server to verify as part of SSL handshake.

  trace.
  
  There are a number of resource name changes between WebSphere

  certificate in a 2-way SSL handshake.
