[satosa-users] "Unknown error" when testing SAML2 backend

* Peter Schober <peter.schober at univie.ac.at> [2020-03-26 14:16]: FWIW, adding an IDP's entityID to the disco URL gets me further: <base>/<name>/disco?entityID=some-idp-entityID lets me see sent attributes and mapped attributes, e.g. [2020-03-26 13:36:35,559] [DEBUG] [satosa.attribute_mapping.to_internal] backend attribute ['displayName'] mapped to displayname [2020-03-26 13:36:35,559] [DEBUG] [satosa.attribute_mapping.to_internal] backend attribute ['mail'] mapped to mail Though I still end up with an "Unkown error" from a yet another KeyError: [2020-03-26 13:36:35,559] [ERROR] [satosa.base.run] [urn:uuid:331aa86e-7f18-4a6f-81b2-f51f21d68c86] Uncaught exception Traceback (most recent call last): File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/base.py", line 289, in run resp = self._run_bound_endpoint(context, spec) File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/base.py", line 229, in _run_bound_endpoint return spec(context) File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/backends/saml2.py", line 353, in authn_response return self.auth_callback_func(context, self._translate_response(authn_response, context.state)) File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/base.py", line 186, in _auth_resp_callback_func internal_response.requester = context.state[STATE_KEY]["requester"] File "/usr/local/venv/SATOSA/lib/python3.7/collections/__init__.py", line 1025, in __getitem__ raise KeyError(key) KeyError: 'SATOSA_BASE' [2020-03-26 13:36:35,561] [ERROR] [satosa.proxy_server.__call__] Unknown error Traceback (most recent call last): File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/base.py", line 289, in run resp = self._run_bound_endpoint(context, spec) File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/base.py", line 229, in _run_bound_endpoint return spec(context) File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/backends/saml2.py", line 353, in authn_response return self.auth_callback_func(context, self._translate_response(authn_response, context.state)) File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/base.py", line 186, in _auth_resp_callback_func internal_response.requester = context.state[STATE_KEY]["requester"] File "/usr/local/venv/SATOSA/lib/python3.7/collections/__init__.py", line 1025, in __getitem__ raise KeyError(key) KeyError: 'SATOSA_BASE' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/proxy_server.py", line 117, in __call__ resp = self.run(context) File "/usr/local/venv/SATOSA/lib/python3.7/site-packages/satosa/base.py", line 307, in run raise SATOSAUnknownError("Unknown error") from err satosa.exception.SATOSAUnknownError: Unknown error I'm guessing this key value comes from satosa/base.py's STATE_KEY="SATOSA_BASE"? Doesn't get me much closer, though. At least the exception happening in _auth_resp_callback_func() is a good sign, as this has this docstring to offer: "This function is called by a backend module when the authorization is complete." So dispite all the tracebacks and exceptions I must be getting close. ;) -peter
