[keycloak-dev] Extend LDAP User Federation Mechanism with TOTP capability

Hello there, I'd like to replace a custom-built authentication system with OpenID Connect via Keycloak. To do so, I intend to extend the LDAP User Federation mechanism (See LDAPStorageProvider, LDAPStorageProviderFactory) to support TOTP authentication. Having implemented my extension as a provider (albeit an extension lacking any additional capability), when I attempt to add an instance of my provider in the Keycloak administration console the 'Required Settings' page contains all of the settings for the LDAP federation I am deriving from, but lacks combo boxes (instead presenting line inputs in their place), and captions against most fields. What can I do to correct this behaviour? Alternatively, is there a more appropriate mechanism for me to provide the behaviour I desire? Any guidance would be greatly appreciated. Regards, Liam M
