Hi,
I am integrating two websites using single sign on. I have two sites
namely
aaa.com and bbb.com.
I enabled SingleSignOn valve in server.xml file, and trying to access
Its not going to work...
Its not because of TC, its because of the way cookies are handled by the
browser.
Its been a long long time since I wrote a filter to do this, and there
are probably better third party products out there.
But this is what I remember...
The SingleSignOn is addressing the issue of sign on across web apps and
within a single TC... not across machines.
ie Tomcat has to at least be able to track the session. If thats covered
then...
Then and I forget the terminology.
A browser will consider this the same domain....
aaa.com/webapp/servlet1
aaa.com/webapp/servlet2
and I think even
aaa.com/webapp2/servlet1
but as soon as that becomes bbb.com
the "browser" treats it like a stranger and does not return the session
key, nor auth info for the other domain... so TC/Apache is screwed
because the browser doesnt want to play.
Vaguely I remember setting "persistent" cookies in the browser, and then
tracking my own cookies across machines... but it also meant a complete
redo of all the security and TC's generic security could not be used.
I remember seeing thrid party tools... but if you cant change the one
webapp, you into something really creative, creating a filter wont work
because security happens before the filter.... you have a creative
problem on your hands ;)
E.g. OpenID, JOSSO etc
Search google for "Java Single Sign On".
As has been stated, SingleSignOnValve isn't a true SSO solution.
p
I think if you can put TC behind Apache, thus getting it back to the
same domain name, and the distinguishing only on sub context...
ie
aaa.com/images/in apache
aaa.com/webapp/someservlet and the call is passed thru to TC
Then the browser will like it and return the authentication details....
otherwise is going to be some kind of complex proxy type thing to trick
the browser.
Good luck...
