WSO2 bridge with id server with zimbra

Would someone be so kind and explain to me how to deploy the zimbra collaboration kit to the wso2 identity server? I know how to get zimbra to use an external ldap server, but I don't know exactly how to make a saml sso bridge between them and put zimbra in the Authorized Applications tab. I am looking forward to your reply. thanks in advance

Edit:

Since I didn't find any solution to integrate zimbra with saml sso, I used their SSO Preauth, more info at http://wiki.zimbra.com/wiki/Preauth
