I have an applications that I would like to use multiple sources with. For example, I have a few users that will live in a native Auth0 database and many users that are stored in a separate LDAP system. Right now I have both activated for the application, but the Auth0 database users credentials don’t work - it’s like the login box isn’t aware of that connections because the LDAP auth still works.

Does anyone have suggestions on what I should do?

Thanks.

Hey there @igelu! Welcome to the community @danalloway 🙂

It sounds like you might be interested in exploring Identifier First Authentication:

> Learn how to configure Identifier First authentication with Universal Login.

At a base level, Ul/Auth0 needs to know which database a user is to authenticate against - Another option is to specify the particular `connection` param in the call to /authorize as outlined in the following FAQ:

[https://community.auth0.com/t/authenticating-users-through-a-specific-connection-database-social-etc/84680?preview\_theme\_id=30](https://community.auth0.com/t/authenticating-users-through-a-specific-connection-database-social-etc/84680?preview_theme_id=30)

This does have the drawback that you can only specify 1 connection, and must implemented in a way (multiple login buttons?) that allows you to make the appropriate call to /authorize.

Hope this helps at least get the wheels turning! 💭
