Assertion with environments which directory names contain hyphens or underscores.

[a-thor@…]

After upgrading Trac from one of the 0.9 betas to the current trunk (checked out few days ago) I got following error while trying to login into some of the Trac environments: Python traceback

Traceback (most recent call last):
  File "/usr/local/lib/python2.4/site-packages/trac/web/modpython_frontend.py", line 206, in handler
    dispatch_request(mpr.path_info, mpr, env)

    dispatcher.dispatch(req)

    assert req.remote_user, 'Authentication information not available.'
AssertionError: Authentication information not available.

After speding some time investigatin the matter I found that "problem" environments all have hyphens in the name of their storage directories. That was not a problem with old (one of 0.9bX) version of Trac. I am not completely sure that problem is in Trac and not in other libraries, as they were upgraded too in the process :) My current environment is RHEL AS 4. Python 2.3 (that comes with it), Apache httpd 2.0.52, mod_python 3.1.4, sqlite 3.2.2, pysqlite 1.1.6. The above error message is taken form another server running on SLackware 10.2 with Python 2.4.1 - so it is obviously not a Python problem. Well, I'm getting short of time right now, but will be glad to provide any additional information in case you need it.

Trac 0.9.5 has this problem also.

It only happens when clicking the "login" button, this problem does not occur if project has forced authentication.

I've been trying to set up authorization on a tracd instance running in a shared hosting environment and have encountered this "Authentication information not available" problem. My home directory on the server contains a hyphen, and several directories in the path to the project contain hyphens or underscores.

Running tracd/0.10dev proxied through apache/2.0.52, python/2.3.4. Redhat CentOS 4.2final

[Devin Ben-Hur <devin@…>]

After further experimentation, hyphens/underscores seem to have nothing to do with this. I renamed or symlinked hyphen-less names and restarted everything. Still get "assert req.remote_user, 'Authentication information not available.'" error when trying login link.

Running tracd daemon proxied by apache; apache has digest authorization enabled and successfully challenges and passes users using the same digest file as trac's —auth option points at.

Devin, it's probably the way you start tracd which is in cause, here. Did you follow carefully the TracStandalone#UsingAuthentication instructions?

[Christian Boos]

This was most likely a misconfiguration of the authentication settings.
