Hi, I have a database with username and password and I want use [DiscourseConnect](https://meta.discourse.org/t/discourseconnect-official-single-sign-on-for-discourse-sso/13045) for use existing users account on Discourse forum.
I don’t understand how retrieve the email and the password that user input info the login form of Discourse.
Into my sso endpoint I receive the query parameters: `?sso=XXX&sig=XXX`
But i need to receive username and password for check into the db…

You will need to create a small web service that connects to that database, and when receives a redirect with those parameters prompts the user for username and password and then redirects the user back to Discourse.

When using [DiscourseConnect](https://meta.discourse.org/t/13045?silent=true) we will just redirect every user login to a service you own, so you have 100% control over the whole signup, login, password requirement, group membership, etc.
