How to configure username?

[darkleaf]

I found option for WMQ::QueueManager.connect: user_identifier.
But client send process uid instead user_identifier value.

Server check user name. It must be "web". But I want run app in docker by "root" user.

I can connect only when this TCP packet contains "WEB" and "web" instead "ROOT" and "root".
Packet info by tcpdump.
