Community Support for OpenDocMan (Deprecated)

I'm a bit of a newbie and was wonder if someone could point me in the right direction.

What would this error message suggest is wrong:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'XXXX_XXXX'@'server209.serverquality.com' (using password: YES) in /home/theduddy/public_html/opendocman/config.php on line 169
Unable to connect: Access denied for user 'XXXXX_XXXX'@'server209.serverquality.com' (using password: YES)

Your mysql user/password combination is incorrect.
