RE: req.connection.user generates AttributeError

Grisha: Thanks for getting back to me on this. I found req.connection.user in the PDF manual dated 4/19/2002, Section 3.3, page 12. And now that I look at the title page, it's for 2.7.8, NOT for 3.0.3. I downloaded the manual to match my installation, and it shows req.user in that section. My apologies for not having RTFMed better--I read, just the wrong one.

RE: req.user always returns None?

Sorry to reply to my own post, but further reading of the list archives got me the solution. I moved the LoadModule directive for mod_python to be first in the list, and voila! it started working right. There was a thread about this in July of this year. Cheers! -- David Hancock | dhancock-Iw1l/lK2TKoAvxtiuMwx3w@xxxxxxxxxxxxxxxx | 410-266-4384 -----Original Message----- From: Hancock, David (DHANCOCK) Sent: Sunday, October 19, 2003 7:58 PM To: 'mod_python-X6cS8wSRu42Ei8DpZVb4nw@xxxxxxxxxxxxxxxx' Subject: req.user always returns None? Now that I'm using req.user instead of req.connection.user, I can get the Tutorial's example authentication code to run without errors--thanks, Grisha, for that. Now, however, the example always returns HTTP_UNAUTHORIZED. I've figured out that this is because req.user is always None. My browser is sending the correct base64-encoded string for the Authorization: header. I'll append additional information. Thanks for any advice.

req.connection.user generates AttributeError

I'm new to mod_python, and I'm stuck already.  I'm working through the examples in the documentation, and even after careful typing (and cutting and pasting from the manual), I can't get the authentication example to work.  The line:         user = req.connection.user Gives an attribute error ('user').  As shown in the manual, I'm calling req.get_basic_auth_pw() first, but still no joy. If I try/except to trap the attribute error, I avoid the 500 Server Error message, but the authentication still doesn't work. Any ideas?  I'm running Windows 2000, Apache 2.0.47, Python 2.2, and mod_python 3.0.3.  (My other computer is a Linux box, but this is what I've got right going right now).  The mod_python is a precompiled binary. I'll be grateful for any assistance I can get.  I'm trying to recreate a mod_perl module (AuthCookie) which implements a ticket-based authentication mechanism.  It works well in Perl, but my group standardized on Python and we'd like to keep using Python for Apache modules, too.

If the swap the first two lines, it will work (regardless of position of LoadModule within the config file). Grisha
