[keycloak-user] keycloak login page toggle

Hello: I have a requirement for a toggle in the login page, between 2 categories If user chooses category 1, ldap should be used for auth, If user chooses category 2, AD should be used for auth. Finally to be redirected to the same client application. Is it possible with keycloak? Does it require development? Any directions will help. I don't find info in keycloak documentation. Thanks in advance. Vidhya
