[Users] Change default users and password in MySQL problems

Hello. I'm David.

I'm working with openser 1.0.1 and MySQL 5.0.18. I'd like changing defaults users and passwords to openser talk to MySQL. I edited "openser_mysql.sh" and I changed some variables in that file. I execute "openser_mysql.sh" and the database was created fine. I wrote next statment in openser.cfg: modparam("auth_db", "db_url", "mysql://user:pass@localhost/openser"). Indeed user and pass are the same in mysql. I run openser but gives an error: 0(0) new_connection: Access denied for user 'openser'@'localhost' (using password: YES)

I don't have any user called openser in MySQL because I changed "openser_mysql.sh". How I change the defaults users and passwords in openser?

Thank you.
