Hello Zend Guru

I wrote a Zend auth class using Zend/Auth/Adapter/DbTable.php with mysql.
My cookie has a dot as in .example.com
I got this in the ini file and it works
The authetications works fine with www but not any other sub domains.

and if I do:
It shows the auth cookie but the session is blank in the subdomains other then www.

What am I doing wrong here?
Do zend session require something like the cookie dot?

Real stupid:
I was starting the Zend_Session in the login class.
Moved it to the bootstrap.
