Re: Zimbra 8 and CAS Authentication

It has been my experience that with a single server installation you may have to change the Zimbra Web Client URL login from

zmprov md domain.name zimbraWebClientLoginURL https://HOSTNAME/zimbra/public/preauth.jsp

zmprov md domain.name zimbraWebClientLoginURL https://HOSTNAME/public/preauth.jsp

I hope that works.

Yep....it's the same CAS that is in use for the production Zimbra instance.

Crazy question but is the cas system running? That looks like the cas server is not putting up its page

Attached is the error. Seems it cannot find the preauth file in the path I'm giving it. But it's there and with the correct permissions.

$ ls -l ~/jetty/webapps/zimbra/public/preauth.jsp

-rw-rw-r-- 1 zimbra zimbra 3767 Dec 16 15:36 /opt/zimbra/jetty/webapps/zimbra/public/preauth.jsp

Unless Zimbra 8 has changed where this file should be placed? That's the only thing I can think is wrong at the moment.....

Yes to the questions from Steve and Pablo...

# ls -l ~/jetty/common/lib/

-rw-rw-r-- 1 zimbra zimbra 87311 Dec 12 18:27 cas-client-core-3.2.1.jar

Plus the file at ~/jetty/etc/zimbra.web.xml.in

I've walked through the documentation several times. I've eliminated the proxy from the mix so I'm talking direct to the mailbox host.

All this is configured as well....

zmprov gdpak domain.name

in the preauth.jsp edit the "public static final String DOMAIN_KEY = " to have your domain key

and edit the default login page location

zmprov md domain.name zimbraWebClientLoginURL https://HOSTNAME/zimbra/public/preauth.jsp

We currently have CAS working just fine in our production 7.2.X install. I have to get this working in my test 8.0.6 instance before upgrading and am not having any luck today.

You put the cas-client-core file on your system? Made sure you referenced your systems proxy server in the zimbra.web.xml.in? ((I'm using 7.2.5 so hope that still applies for 8))

Anyone familiar with using CAS authentication in Zimbra 8? I've got it all configured but when I try to browse to the URL:

https://HOSTNAME/zimbra/public/preauth.jsp

I get a 404 not found error. The preauth.jsp file exists in ~/jetty/webapps/zimbra/public/. It's owned by zimbra:zimbra and chmod'd 664.
