Question

I have TWikiUserAuthentication set up with Partial_Authentication on only selected webs. Everything works fine, except for the redirect to the oopsauth template, which is where I would like users to land if they request some protected page, or edit script, so that they can register or change their passwords if they can't login.

I found PartitialAuthenticationForcesAllUserToAuthenticate, which applied to me, but it does not address my issue specifically.

I have the following line in my cgi-bin/.htaccess:

ErrorDocument 401 /cgi-bin/oops/TWiki/TWikiRegistration?template=oopsauth

If you manually browse to http://twiki.svsoliton.net/cgi-bin/oops/TWiki/TWikiRegistration?template=oopsauth, it works just fine. But if you try to access any protected page, or viewauth, or even just to the home index.html, and cancel out of the authentication dialog, it will return this error page:

This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request. Apache/2.0.46 (Red Hat) Server at www.svsoliton.net Port 80

My server access-log file contains the following lines:

207-171-180-101.amazon.com - - [16/Dec/2005:09:27:51 -0600] "GET / HTTP/1.1" 302 313 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; en) Opera 8.51"

The only entry in the server's error-log is:

[Fri Dec 16 09:27:51 2005] [error] [client 207.171.180.101] Premature end of script headers: oops

The only entries in the data/debug.txt file is like this:

This may be unrelated, but looks suspicious to me, even though everything else seems to work without a problem: I am running on an Ensim-based hosted server, and I installed TWiki on a "subdomain". Several of the lines reported by testenv look "wrong" to me. Here is a list of what I see and what I would expect to see:

name	testenv reports	expected
DOCUMENT_ROOT	/var/www/html	/var/subdomain/twiki/html (which is a link to /home/twiki/public_html
HTTP_HOST	twiki.svsoliton.net	this is fine, but see SCRIPT_URI and SERVER_NAME
SCRIPT_URI	http://www.svsoliton.net/cgi-bin/testenv	http://twiki.svsoliton.net/cgi-bin/testenv
SERVER_NAME	www.svsoliton.net	twiki.svsoliton.net
SITE_CGIROOT	/var/www/cgi-bin	not sure, although twiki's cgi root is /home/twiki/public_html/cgi-bin
SITE_HTMLROOT	/var/www/html	see DOCUMENT_ROOT

Maybe I need to read up on apache's environment variables.

I DO NOT HAVE ACCESS to httpd.conf! Neither do I have shell access, only ftp.

My actual bin and lib directory paths are:

bin: /home/twiki/public_html/cgi-bin
lib: /home/twiki/public_html/cgi-bin/lib

I am attaching TWiki.cfg and the cgi-bin/.htaccess file. Please note that I had to set the path to my data directory's .htaccess file like this, before I could get it to work:

AuthUserFile /home/virtual/site236/fst/home/twiki/data/.htpasswd
