verify() actually doesn't accept unicode arguments
We really don't need to be too clever guessing types

Every implementation I've seen uses pointer types for gss_name_t, etc.
GSS_S_BAD_MIC isn't defined in MIT Kerberos

It's deprecated and GSS_S_BAD_SIG should be used instead.
Erm, how did I miss this ...
None is not convertible to NULL anymore in cffi
Fix completely wrong usage of name_buffer
Because we're importing everything in setup.py, setup_requires everything
Make sure the MechName is valid-ish
Make the integration tests runnable
Change mentions of ctypes in doc to describe cffi
test for context lifetime
