Hi,
I was working with sakai and CAS and I got it working fulfilled.
Now, I want to use clustering and load balancing to improve the server
performance, but I have some problems.
Before to my problems, my configuration:
- Note: all the instances are in the same computer
- Apache 2.2 to load balancing, with the following configuration:
<Proxy balancer://cluster>
BalancerMember ajp://168.176.135.60:8009 route=server0
BalancerMember ajp://168.176.135.60:8010 route=server1
</Proxy>
<Location />
ProxyPass balancer://cluster/ stickysession=JSESSIONID nofailover=Off
</Location>
<Location /balancer-manager>
SetHandler balancer-manager
AuthType Basic
AuthName "Cluster manager "
AuthUserFile /home/edwintriana/server/apache_2-2/conf/.htpasswd
Require valid-user
</Location>
- In each configuration of sakai-login-tool

</servlet-mapping>
Now the PROBLEM:
When I write the url en my browser
http://telemedic60.telemedic.unal.edu.co:8080/portal and I got the gateway
of sakai. then i click in the cas button y I am redirected to the cas
server, I put my name and password, than I am redirected to sakai, but, I am
redirected to the cas logout automatically.
I don't what is wrong.
I appear that you understand me.
Thanks!!!
