NB: Don't store the user's credentials in the config file, and don't store them using SHA1.

SHA1 has been broken since 2005, and completely dead since 2016.

You should also choose more secure passwords, and don't store a plain-text copy of the password in the config file.

If the application doesn't use role based management system, SSO is useless, because anyone can access to the application. In other words, there's no matter what user and what role he has.
