authentication problem: won't log in... but won't give error

I'm trying to set up htdigest authentication for trac. When
I run
tracd and click on the "Login" link in my browser,
I am not given a
login dialog box. It simply re-fetches the same page from
trac and
shows it to me again, just as if I'd hit the refresh
button.

When I click on the login link, the access log says this:

76.170.239.27 - - [31/Aug/2007 13:04:33] "GET /trac-biz
HTTP/1.1" 200
-
76.170.239.27 - - [31/Aug/2007 13:04:40] "GET
/trac-biz/login HTTP/
1.1" 401 -
76.170.239.27 - - [31/Aug/2007 13:04:40] "GET
/trac-biz/login HTTP/
1.1" 302 -
76.170.239.27 - - [31/Aug/2007 13:04:40] "GET /trac-biz
HTTP/1.1" 200
-

...and trac.log says:

2007-08-31 13:08:25,354 Trac[api] DEBUG: Updating wiki page
index


This is the auth file: -rw-r--r-- 1 apache apache 343 Aug 31
12:47 /
srv/www/trac-biz/conf/users.htdigest

...and this is how I'm starting tracd:

sudo -u apache tracd -p 4001 --auth
trac-biz,/srv/www/trac-biz/conf/
users.htdigest,foo_biz_trac /srv/www/trac-biz &

Here's a line from the auth file:
rick:foo_biz_trac:21ee53b4d5d63ef17645d80f212fbffc


Everything looks like it should work, but it doesn't- any
help or
ideas would be greatly appreciated!

Thanks!
