[Users] user 'admin' and mysql

Hello, I just noticed that openser_mysql.sh creates the username "admin" with the default openserrw password in the subscriber table. This seems to introduce a security hole where a well-known username and password pair would exist on most virgin openser installations. Is there a good reason to have that entry in the "subscriber" table? Is it used anywhere? Now I know that we're supposed to change the mysql access passwords, but I have to admit that I didn't think to change a password actually emebedded IN the data of the mysql database. Did I miss a critical security note somewhere alerting me to this default user? Thanks, -mark
