ZeppelinContext not available in pyspark

When I try to access the ZeppelinContext in pyspark, I get the following error:

%spark.pyspark
print z

Which prints out the following:

{}

I'm trying to access AuthenticationInfo. I would ideally like a way where some user object would be globally available (i.e. my own 3rd party module can access it somehow so I can pass that to a custom API) - any good way to do that?
