DataObject and Username

Hi, I'm looking for a way to, if a configuration option is set, connect to a database using my own username and password instead of the ones given in the 'database' option of DB_DataObject. That is, I want to use the info given by a user at login to connect to the database instead of the one given in the 'database' option. I've currently got code that seems to do this some of the time (immediately after login) by overriding the _connect() method and changing the DSN if the option is set. However, the changed DSN doesn't seem to survive after that one use, it gets reset to whatever is in the config file. The idea is to get it so that 'Updated By' will list the correct username as opposed to the default one given in the DataObject config file. Any suggestions as to how this could be done?
