I ´ve got it running. ZMYSQLDA could not find the libraries from mysqldb. Yes, you´re right, it was a FAQ. BTW: Is there any product that acts as acl_users which allows to collect more information from my users, like company name, adress ... ?

Hello Peer, We've got the other "half-empty bottle" for that pb. We have built a product (ZAnnu) with people's informations for differents organizations hosted within a MySQL base, and we are on the proccess to use GUF (waiting for a stable LoginManager) as an acl-user replacement (end of this week or next week). Should be cool to share our experiences on that, and i can improve ZAnnu if some functions are missing. http://www.zope.org/Members/dgeorgieff/ZAnnu. Didier Georgieff
