requests-kerberos 0.8.0

Authentication Failures

Client authentication failures will be communicated to the caller by returning the 401 response.

Mutual Authentication

By default, HTTPKerberosAuth will require mutual authentication from the server, and if a server emits a non-error response which cannot be authenticated, a requests_kerberos.errors.MutualAuthenticationError will be raised. If a server emits an error which cannot be authenticated, it will be returned to the user but with its contents and headers stripped.

>>> import requests
>>> from requests_kerberos import HTTPKerberosAuth, OPTIONAL
>>> kerberos_auth = HTTPKerberosAuth(mutual_authentication=OPTIONAL)
>>> r = requests.get("http://example.org", auth=kerberos_auth)
...

>>> import requests
>>> from requests_kerberos import HTTPKerberosAuth, DISABLED
>>> kerberos_auth = HTTPKerberosAuth(mutual_authentication=DISABLED)
>>> r = requests.get("http://example.org", auth=kerberos_auth)
...

Logging

This library makes extensive use of Python’s logging facilities.

Log messages are logged to the requests_kerberos and requests_kerberos.kerberos_ named loggers.

If you are having difficulty we suggest you configure logging. Issues with the underlying kerberos libraries will be made apparent. Additionally, copious debug information is made available which may assist in troubleshooting if you increase your log level all the way up to debug.
