[keycloak-user] Creation UI for new authentication schema configuration.

Hi all, I want to add support for the new authentication schema. How can I add UI for new authentication schema configuration? For example, I want to add the TACACS authentication schema. Therefore I need to configure the TACACS server IP and the secret. May be I have missed but I can not find it here: https://keycloak.gitbooks.io/server-developer-guide/content/topics/auth-s... Thank you in advance for your help. Best regards, Michael
