[keycloak-user] add self signed certificate for external IDP without root acces

Hi, It may be a wildfly issue but i'm not sure. I'm not root on the server (i can't do an update-ca-trust) i configured an external IDP, when keycloak wants to exchange the code for the ID token to the external IDP, i get a certificate exception. I tried adding the certificate in the keystore. There is no trustore.jks in the standalone.xml, i guess it's using the system trustore Should i create an empty trustore.jks and try to put it in the standalone.xml ? but i might loose other external IDP with real public certificate. I'm sure it's very simple, but i can't get it to work. I'll take any hints I'll update if i find the solution. Thanks Amaury
