> When connecting from Python using SPNEGO as the authentication mechanism an exception occurs:
> {{import phoenixdb}}
>  {{import phoenixdb.cursor}}
>  {{database_url = 'http://myphoenixdbserver:8765/'}}
>  {{conn = phoenixdb.connect(database_url, autocommit=True, authentication="SPNEGO")}}
> Causes the following exception:
> {{venv/lib/python3.6/site-packages/phoenixdb/avatica/client.py:121: RuntimeWarning: Unexpected end-group tag: Not all data was converted}}
> {{ if not err.ParseFromString(message.wrapped_message):}}
> {{Traceback (most recent call last):}}

> {{ return Connection(client, **kwargs)}}

> {{ File "venv/lib/python3.6/site-packages/phoenixdb/avatica/client.py", line 96, in raise_sql_error}}
> {{ raise errors.InternalError(message, code, sqlstate)}}
> {{phoenixdb.errors.InternalError: ('', 0, '', None)}}
> This exception is caused because phoenixdb is using Kerberos 5 instead of SPNEGO.
> To resolve this issue, we have prepared a patch following the idea described in the "Explicit Mechanism" section of [requests-gssapi|https://pypi.org/project/requests-gssapi/]. The attached patch fixes phoenixdb so that SPNEGO can be used to authenticate.
> If you want, I can create a branch and pull request for this.
