Gateone with PAM Auth not working anymore

[BenSchweikert]

Hi, I am using Gateone in the official docker image with pam auth. This was working until some days ago. What I did since than:

• Upgraded host to ubuntu 14.10 - docker is untouched
• at the start of the docker there is a git pull from the gateone-github repo

Error message in browser: Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 1288, in _stack_context_handle_exception raise_exc_info((type, value, traceback)) File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 1475, in wrapper result = method(self, _args, *_kwargs) File "/usr/local/lib/python2.7/dist-packages/gateone-1.2.0-py2.7.egg/gateone/auth/authentication.py", line 559, in get self.get_authenticated_user(self._on_auth) File "/usr/local/lib/python2.7/dist-packages/gateone-1.2.0-py2.7.egg/gateone/auth/pam.py", line 63, in get_authenticated_user self.auth_basic(auth_header, callback) File "/usr/local/lib/python2.7/dist-packages/gateone-1.2.0-py2.7.egg/gateone/auth/pam.py", line 87, in auth_basic callback(user) File "/usr/local/lib/python2.7/dist-packages/gateone-1.2.0-py2.7.egg/gateone/auth/authentication.py", line 568, in _on_auth self.user_login(user) File "/usr/local/lib/python2.7/dist-packages/gateone-1.2.0-py2.7.egg/gateone/auth/authentication.py", line 159, in user_login user_dir = os.path.join(self.settings['user_dir'], upn) UnboundLocalError: local variable 'upn' referenced before assignment

Any ideas? Ben

Confirmed here, same error, same distro.

Seems to bypass if commenting 157 of .../gateone/auth/authentication.py

       # NOTE: These bytes checks are for Python 2 (not needed in Python 3)
        #if isinstance(user['upn'], bytes):
        upn = user['upn'].decode('utf-8')

Hello,

same error, doesn't change if I comment line 157 in /usr/local/lib/python2.7/dist-packages/gateone-1.2.0-py2.7.egg/gateone/auth/authentication.py

same problem on Ubuntu 12.04 LTS and Ubuntu 14.04 LTS

Ok working fine now: Added:

upn = "initvar"

before:

if isinstance(user['upn'], bytes):
      upn = user['upn'].decode('utf-8')

I don't know anything about python...but it works now.

[iqt4]

Understanding the comment, I would suggest a coding like this:

# NOTE: These bytes checks are for Python 2 (not needed in Python 3)
upn = user['upn']
if isinstance(upn, bytes):
    upn = upn.decode('utf-8')

I will test it the next weekend, and I will drop a feedback here.

[liftoff]

I will have a fix for this pushed later tonight.

[liftoff]

Anyone try the latest code? Does it resolve the problem? It should.

[phealy]

It fixed it for me, thanks.
