Title:
deletion of token for client causes failure
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Used a script to get a token, use that token to delete a server, then
delete the token (in an effort to cleanup). The server deletion got
stuck, and the following error was logged:
unsupported operand type(s) for +: 'NoneType' and 'str'

in authenticate
token_url = self.auth_url + "/tokens"
Deleting the token when the client is done with it should not cause a
problem. If OpenStack needs a token internally, it should get one
itself. And indeed we found that the code tried to do just that when
the token created by the test script stopped working, but the
reauthentication code is flawed... it does not have the auth_url,
which led to the error shown in the stacktrace.
