[keycloak-user] Disabling token issuer check

Hi All, While trying to validate 2rd party token in a NATed environment, we are getting error in verifying the token, due to difference in the issuer of the token. Getting error like org.keycloak.common.VerificationException: Invalid token issuer.Expected "keycloak-service-url" but was ' https://boxip:30003/auth/realms/myrealm' We are using stable helm chart for deploying keycloak. Actually there is a check to enable/disable realmUrlCheck(i.e the issuer check). If disabled we are good to go. Then we are able to verify third party token in NATed environment too. My question is, will there be any security concern if we disable this checkRealmUrl check in the adapter. Thanks & regards Kapil
