Got the same problem, running mod_wsgi/python2.5 and Trac-0.11.6. Tried to update everything, seems uptodate. Removed egg-cache and older egg-files. Still same issue. No login through webui, no password reset, no new user registration. Perhaps the full Traceback can help...

[luis.kop@…]

it happens to me as well.

What's the solution?

[luis.kop@…]

Downgrade to 0.11.1 solve for now

This isn't a solution, just a workaround.

The solution is for the author to fix this bug. I'm sure it's not hard, but I doubt he/she has read this bug report.

If anyone knows how to contact the author directly, that might help.

[John Hampton]

OK, sorry for the late response. Can anyone provide me with a bit more info? Does this only happen with the SessionStore backend? Does it also happen with htdigest or basic auth?

I don't know why the behavior changed between 0.11.5 and 0.11.6, I'll have to take a deeper look at the changeset for 0.11.6.

On line 45 of acct_mgr.pwhash​ change:

    realm = Option('account-manager', 'htdigest_realm')

to

    realm = Option('account-manager', 'htdigest_realm', '')

It's untested, but may work. I'll be at PyCon later this week and will have some time to investigate further and commit a fix.

I have the same problem. The fix above worked for me. I'm using trac 0.11.6 and account manager plugin 0.2.1dev with Python 2.5.1.

[yonas.y@…]

Works for me too! :)

[John Hampton]

(In [7706]) Add default empty realm to the htdigest_realm

Closes #6453
