[keycloak-user] Alternative SP login

Hi all, For our application it is important that there is an alternative login mechanism for KEYCLOAK-SAML. Wildfly/Undertow already support this mechanism for SPNEGO (SPNEGO,FORM with FORM as fallback for instance). For SAML this could be achieved by allowing an excluded URL, which is not redirecting to the IDP, showing the a form for FORM authentication. What are your thoughts on this feature? Or is there an existing thread on this subject? Thanks in advance. Kind regards, Mark
