Troubleshoot an IBM WAS connection

The XL Deploy WebSphere Application Server (WAS) plugin uses the wsadmin tool to perform tasks. When XL Deploy starts wsadmin on a server for the first time, you must interactively accept the dmgr certificate. XL Deploy cannot do that, so it will hang if you do not accept the certificate. This is an example of the output that appears in the step log:

SSL SIGNER EXCHANGE PROMPT ***
SSL signer from target host null is not found in trust store /opt/ws/6.1/appserver/profiles/AppSrv01/etc/trust.p12.
Here is the signer information (verify the digest value matches what is displayed at the server):

Add signer to the trust store now? (y/n)
