Flask-kerberos Yields Different Results When Running The Code Via "flask Run" And With Vim

Simply saying there is a Flask App based on the Flask-Kerberos example with a valid keytab file (os.environ['KRB5_KTNAME']='/path/to/file.keytab'). This is a working tree of my pro

Solution 1:

When you use flask run, it imports your app as a module, therefore __name__ will not be equal to "__main__", therefore init_kerberos() never gets called and never sets the _SERVICE_NAME global within flask-kerberos.

Also, generally, I would suggest switching to flask-gssapi, both because it is written in a cleaner manner and does not rely on global state, and because it is based on python-gssapi instead of the old & nearly unmaintained pykerberos.
