[Serusers] SIP registration with openser

I've set the SIP_DOMAIN environment variable, (the IP of the pc where I'm running the openser and then the same command but with the IP where I've a sopftphone on a XP pc) and then I've run this: openserctl add 650 1234 650@192.16.25.12 (650 is a softphone registered on 192.16.25.10...a XP pc)(I've made also with 650@192.16.25.10..but doesn't change...)

Mysql password: (empty I think) MySql password for user 'openser@localhost': (empty) Enter password: (root password )

ERROR 1045 (28000): Access denied for user 'openser'@'localhost' (using password: YES) introducing the new user to the database failed

Where is the problem? Which are the right passwords?....I'm using openser on an asterisk at home box..
