AccountManager LoginModule fails with error "can't set attribute"

Reported by: pickscrape Owned by: mgood
Priority: normal Component: AccountManagerPlugin

Cc: Trac Release: 0.10

Description

When using the LoginModule we get the following error when submitting the login form:

2006-03-22 01:21:32,264 Trac[main] ERROR: can't set attribute

AttributeError: can't set attribute

I've had a quick look at the code myself but can't see anything obvious.

  • Resolution set to fixed
  • Status changed from new to closed

(In [532]) req.remote_user can't be set as a property after the WSGI merge, so set it in the WSGI req.environ instead (fixes #234)

  • Resolution fixed deleted

  • Trac Release set to 0.10

I have this problem, too; not sure if it's the same cause but it's certainly the same error message and also occurs when logging in. This is with Trac 0.10.

Error message:

The only thing I can see is that I'm running Python 2.3 as opposed to 2.4—could that be a problem?

This happens when trying to log in with any user. When trying to register a new account, I get this message:

Replying to r@robm.me.uk:

I have this problem, too; not sure if it's the same cause but it's certainly the same error message and also occurs when logging in. This is with Trac 0.10.

There are two versions of the plugin: one for 0.9 and one for 0.10 and you've installed the 0.9 version. Check the installation instructions and install the 0.10 version instead.

Forgive my stupdity—I'm new to Trac—but how do I do this without access to the administration panel?

I've downloaded the "eggs" for WebAdmin and AccountManager, and run "easy_install" on them. I kill my fastcgi process, and now the link to log in is gone.

I poke around my config, and figure I should set the following line to enabled:

trac.web.auth.loginmodule = disabled

Which brings up the Login link, but when I click it I'm hit with the following error:

AssertionError: Authentication information not available.
