AttributeError: 'module' object has no attribute 'auth'

The following one-line fix seems to solve the problem for me:

--- subsystem/webFront/lib/nav/web/auth.py.orig Tue Mar 13 11:59:25 2007 +++ subsystem/webFront/lib/nav/web/auth.py Wed Mar 14 12:09:35 2007

[...]

However, I wouldn't expect a bug like this to slip into a release, so I have to wonder if something else is wrong - a missing PythonOption perhaps? Unfortunately, I'm not very familiar with Python.

Actually, there is some historical weirdness with importing submodules under mod_python. I think it has been fixed in newer versions, but the bugs are still present in Debian/sarge (mod_python 3.1.3).

To try working around these import problems, nav does some rather odd importing of modules from a lower point in the package hierarchy. The nav module itself imports the nav.auth module into its own namespace (as 'auth'). Although nav.web.auth (the one you've patched above) doesn't explicitly import nav.auth, it imports nav, which has the symbol 'auth' in its namespace. That's why this (normally) works.

So why it suddenly doesn't work at your end I can't be sure of, because there have been no changes to this code that I'm aware of. A situation where it might fail, though, is if the nav module failed to import the nav.auth module for some reason.

I'm going to take a closer look at this import circus when Debian/etch is released as the next stable version, but your patch might solve the problem at hand, as long as it doesn't break anything for anyone else (thanks!).
