Update Password field for a Database conection

Hello,

I have a data base connection whos password changes every sometime. When I update the password in the configuration for data bases connections and test the connections all look great, BUT when I execute the data sources when I used that database connection it seems like the password has not been updated, and it fails due to incorrect user name or password :(. SOMEBODY HELP I have a lot test cases and it is very awfully update all data sources to get the new password correctly in each of those.
