   should work also with other database. The auth_db module
   works.

1.5. Installation & Running

1.5.1. Installing

   Prerequirement: you should first install unixodbc (or another
   program that implements the odbc standard, such iodbc), your
   database, and the right connector. Set the DSN in the odbc.ini
   file and the connector drivers in the odbcinst.ini file.
     _________________________________________________________

1.5.2. Configuring & Running

   In the openser.conf file, add the line:
....
loadmodule "/usr/local/lib/openser/modules/unixodbc.so"
....

   You should also uncomment this:
....
loadmodule "/usr/local/lib/openser/modules/auth.so"
loadmodule "/usr/local/lib/openser/modules/auth_db.so"
modparam("usrloc", "db_mode", 2)
modparam("auth_db", "calculate_ha1", yes)
modparam("auth_db", "password_column", "password")
....

   and setting the DSN specified in the odbc.ini, inserting this
   with the url adding this line:
....
modparam("usrloc|auth_db", "db_url",
    "unixodbc://openser:openserrw@localhost/my_dsn")
....

   replacing my_dsn with the correct value.

   HINT: if unixodbc don't want to connect to mysql server, try
   restarting mysql server with:
shell>safe_mysqld --user=mysql --socket=/var/lib/mysql/mysql.sock

   The connector search the socket in /var/lib/mysql/mysql.sock
   and not in /tmp/mysql.sock
