.. re-synchronising..
I've made some progress. I have a VirtualHost, so I had to add a "JkMountCopy 'on'"
inside the <VirtualHost>, and now, it's at least proxying through to the Tomcat using
mod_jk!!
BUT, it's still not logging me into the Tomcat :(...
I don't want to post the entire jk.log, so can someone point me to what to look
for in there, maybe?
Ok, so let's now continue on the mod_jk track, since you've got that part
running.
What you are looking for, is an AJP "request attribute" named "remote_user" (lowercase),
in the packets which mod_jk sends to Tomcat.
I don't know if that would be in the log, nor if there is any way to coerce mod_jk into
putting it in the log.
But since your Tomcat is not authenticating, chances are that it isn't there.
So let's try to cheat, and force it to be there.
In your Apache configuration, add this line :
JkEnvVar remote_user "blablabla"
and let's see what happens.
(and after that, we'll try mod_rewrite or a combination)
Andre,
I had already tried including a "JkEnvVar" as you suggested in my httpd.conf,
in order to try to hard-code getting SOMETHING to show up, but no joy :(...
I've also tried a bunch of other variants:
JkEnvVar REMOTE_USER
also:
JkEnvVar remote_user "foobar"
also:
JkEnvVar AJP_REMOTE_USER "foobar"
Nothing works :(...
This is really getting discouraging :(. It almost seems to me like that
'tomcatAuthentication' functionality doesn't even exist at all.
I've searched the jk.log for multiple things, "attr", "remo", etc., and find
nothing relevant/significant at all in there...
Do not get discouraged. I can guarantee that the tomcatAuthentication="false" works, when
the Apache front-end really does authenticate the user. I use this all the time.
(Just not with the same SSO mechanism as you).
I also know that "JkEnvVar" does work in general for setting request attributes at the
Apache level, and have them passed to Tomcat by mod_jk, because I also us that regularly.
(And there exists a similar functionality in mod_proxy_ajp).
What may not work in the trials above, is that specifically this "remote_user" request
attribute may be overwritten by mod_jk or mod_proxy_ajp, even when you have set it
explicitly in Apache.
After all, this feature is designed to do one thing : examine the "request record" of
Apache for an authenticated user-id, and if one is set, pass it along to Tomcat over the
AJP channel. If mod_jk/mod_proxy_ajp do not find such a user-id in the request record,
they may just /clear/ the remote_user attribute, thus voiding our attempts at cheating.
To verify this is relatively simple.
Create the following <Location> section in Apache :
<Location /sampleajp>
AuthType Basic
AuthName "toTomcat"
AuthUserFile /some-path/passwords
Require user testuser
SetHandler jakarta-servlet
SetEnv JK_WORKER_NAME tomcatA (<- or whatever name your worker has)
<Location>
Note: the SetHandler and SetEnv lines above, in that <Location>, are equivalent
to saying :
JkMount /sampleajp/* tomcatA
Then follow the instructions here to create the password file and the user
"testuser" in it :
http://httpd.apache.org/docs/2.2/howto/auth.html
section : Getting it working
If you try to access such a URL "/sampleajp/*", the browser will popup a bssic auth dialog
and force you to login.
This will result in the request being duly authenticated for Apache, which /will/ result
in the Apache user-id being passed to Tomcat.
Then, once you have verified (in Tomcat) that it is so, have another look at the mod_jk
logfile, to see if then you spot the attribute being passed.
(You will know that it is passed, but it may still not show up the logs).
If all of that works, then we know that in order for your scheme to work, you must somehow
force the user-id obtained by your SSO system, to be also set in the Apache request
record. Which should be a solvable problem.
And if not, then you still have your Valve..
