CMIS Android Browser - How is the username and password sent to the server?

[Sagara Paranagama]

Hi all,

I'm trying to access my implementation of the CMIS server through the
android CMIS Browser app (downloaded from the play app store). However when
getService(CallContext context) is invoked, the context object does not
contain the username and password. Is this expected?
If so, how can I get the username and password?

Thanks,
Sagara
