SAP PI 7.1 JMS Adapter: Add principal and security credentials

For SAP PI 7.1, is there a way to add user name and password to InitialContext for JMS adaptor?

I cannot see the Initial context parameters as in PI 7.3.1 JMS Adapter UI. I need to add the user name and password to avoid JMS Security exception.

If yes, what is the property to add?  Been searhing and trying for a while.

rgds,
