PHP cookie and Zimbra

[NoDoze]

I have our intranet site integrated with zimbra via a Home tab.

I need each user logged into it so that it can pre-poulate certain areas of the website based on the user.

I wanted to know how to determine user from the ZM_AUTH_TOKEN cookie?
And how could I add cookie info to the mail.domain.com that the cookie is under. Cause it zimbra cookie doesn't seam to allow it...?

I was thinking of maybe changing the zimbra default cookie from mail.domain.com to domain.com then I could use the cookie info across sub domains, but that looked complicated. Is it even possible?

I'm open for suggestions...

Thanks!

ok, I found this:
Preauth - Zimbra :: Wiki

...which got the login part...

...but I still don't understand how to add cookies to mail.domain.com, or verify user passwords

Thanks

Using pre-auth no user password is required. Once the token has been generated you set the ZM_AUTH_TOKEN cookie and any further HTTP(s) SOAP requests etc, by that user, will be authorised.
