test_server does not capture sasl output

[Reto Kramer]

In one of my testcases sasl prints information to the terminal that I 
start the testrun from (I use the batch option, so no new window is 
opened). I had hoped that sasl output would be captured per testcase 
like io:formation material is.  Is this a bug, or do I have to do 
something special to capture the sasl reports (ideally associated with 
the test case that triggered them)?

Thanks,
