Yes clients from entity descriptors. i don't understand import the file part. Where to import the file? I have both IDP(picketlink) and SP(keycloak) under my web-INF file. but, i don't see any SAML communication between SP and IDP happening.
I am new to SAML and for beginner,picketlink has so many example for both IDP and SP which is awesome and gives clear picture of whats need to be done. But, Those example are missing for keycloak SAML Service provide. only three example are for keycloak and that too some how not detailed.
