Pass a whole krbV.CCache object to ldap2 connect() method so that
it can properly detect both type and name of a CCAHE. Otherwise
the test fails on systems with default DIR type CCACHE.
The changes include:
* Change license blobs in source files to mention GPLv3+ not GPLv2 only
* Add GPLv3+ license text
* Package COPYING not LICENSE as the license blobs (even the old ones)
mention COPYING specifically, it is also more common, I think
