[Serusers] Multiple domain

Hi ! A have a small technical question:) It considers serving of multiple domain. I would like to make sure that I understand things right. After I read the user doc and README from domain module I came to the following state of art:) 1)one has to create the seperate location and subscriber table for each domain *so if i have for instance two domains : dom1.com and dom2.com then my ser has to have the according dns records in the dns server? 2) after creating the tables i need to add domains record in the database to the domain table *I dont know why but when ever i try to add or show domains o get the following error 500 command 'domain_dump' not available - why is that so? any way instead of an error the serctl command adds the domain record to the database 3) modify the ser.cfg file - add appropriate modparam commands 4) modify the ser.cfg file by adding a regular expression analizys to invoke the save, www_chalenge, proxy_chalenge and lookup correctly with the right domain? Please tell me is my thinking here right? or maybe there is another way As allway thank u for your time. Bests tomek
