Now i have preauth working in my machine, but the problem is:
I don't know how to use this mechanismeto do SSO in Liferay (where a have other application deployed Alfresco,...)
for zimbra i decide to use IFrame (a liferay protlet) that gives possibilities to invoke web application to Liferay Portal.
So any one can tell me or give me a piste to use preauth mechanisme to do SSO on Liferay ??
Sorry for my bad english
