issue with apache proxy to tomcat with apache simple authentication.

authentication proxy tomcat httpd

[infinitiguy]

Hey all,
Here's what I'm trying to achieve. I have a tomcat application deployed on another server and have configured apache to proxy to it using mod_jk. Works great. So, if I go to [huskar...] apache reads through, does some rewrites and sends me to [huskar...] (which is actually [luna:8080...]

Now, I want apache to do some simple authentication. I downloaded and loaded mod_auth, created a htpasswd file, and put in the following configuration.. (ignore, or pay attention to, the commented stuff... I was trying a bunch of different things).

I read online that location should be used when you're protecting a url and not a actual filesystem on the apache host.. Once this is enabled, it does prompt me to login, and I login, but then it forwards me to a blank page(the redirect works), so I end up at [huskar...] but it seems like it stops responding. However, if I do... [huskar...] (the admin page) it authenticates me(if I close my browser) and redirects me fine... which is really bizarre.

If I disable authentication, both work.

Below is my location statements, as well as the redirects I have in place..

Any help is most appreciated.

and for fun... my jk statements.

Did you check if one of both logs (mod_jk.log and error.log) contains some relevant entries regarding your request?

Apache itself shouldn't respond with an empty page 0 byte page (status code 200 in your case?), mostly some content handlers which don't return a body nor an error status are producing such results.

Once this is enabled, it does prompt me to login, and I login, but then it forwards me to a blank page(the redirect works)

it authenticates me(if I close my browser) and redirects me fine

Since you described that two times in that order, I'm wondering what's going on at your server.
The processing with your setup should be
request by client - rewriterule matched (hook_uri2file) --> redirect

new request by client -> rewriterule didn't match -> jk_translate -> jk_map_to_storage -> no credentials/auth check not passed --> Auth response 401

new request by client -> rewriterule didn't match -> jk_translate -> jk_map_to_storage -> check user_id/authenticated -> auth check passed -> jk_handler

You may check if you reach the handler with

JkLogLevel debug

or trace since mod_jk should log something.

Well, I enabled debug logging in mod_jk, but Im not really sure what to make of what I'm seeing.

When it works right, there are thousands of lines written to mod_jk.log, when it doesn't work right, there's only a few dozen.

btw, I've changed systems to move to the one im actually working on, so apache/tomcat both live on the same host(uxwebprep) instead of two separate hosts like before. The configs are the exact same though.

The logs don't seem to tell me anything interesting, but maybe I don't know what I'm really looking for?

tail of log when it does work(auth is disabled).

this is actually resolved now. It was a lack of existing user account names on the clearspace instance. I did not realize that the basic authentication was going to take my username that I logged in with, and pass it directly into clearspace. So when I was logging in with dmurphy, it was taking it, and putting it right into clearspace. Since that user didn't exist, it just gave me a blank page. As soon as I created a user of dmurphy in clearspace, it passed me through.

I'm surprised that I didn't get any errors or anything kind of hinting to that.

The log shows us that mod_jk connects successfully to tomcat but tomcat replies with a "Content-Length 0" header.

I'm surprised that I didn't get any errors or anything kind of hinting to that.

I don't know tomcat well, but may be there are some logs, too.

As soon as I created a user of dmurphy in clearspace, it passed me through.

Maybe you can set tomcatAuthentication=false in conf/server.xml since apache http server checks if you're authenticated or not?

<Connector port="8009"
  enableLookups="false" redirectPort="8443" debug="0"
  protocol="AJP/1.3" tomcatAuthentication="false"/>

BTW: Since your domain and password are present in the logs, may be remove the snippet.
