[Serusers] MySQL confusion

Hello, I'm a complete newbie to SER and I'm having a problem following the MySQL section of the "getting started" guide. Whenever I try to use serctl to add a user I get access denied; LabServ1:/home/chris# export SIP_DOMAIN=mylab.com LabServ1:/home/chris# serctl add test1 test1pass test1(a)mylab.com MySql password: ERROR 1045: Access denied for user: 'serro@localhost' (Using password: YES) error: SER/FIFO not accessible: 2 LabServ1:/home/chris# I think this may be down to the MySQL install. I've installed MySQL and tested it, however I can't find any documentation anywhere to show me what users, tables and databases to setup for SER. I'm using SER on Debian. It's quite possible I'm missing something obvious. I'd appreciate a pointer in the right direction. Chris
