I'm using
jboss keycloak 1.5 final version.
I developed
my custom user federation provider interfacing with
keycloak properties and my user enterprise database.
My need is
to send up to user the login interface custom error
messages based on particular specific error related to my
legacy user db.
I saw
keycloak themes have a resources folder by which i can
localize and add new messages. Then i can reference them
by angular js using
$myMessage
notation.
The problem is i want to rise up a message from keycloak
server. My user federation provider implements
UserFederationProvider interface. So i should have to
override:
@Override
public
CredentialValidationOutput validCredentials(RealmModel
realm, UserCredentialModel credential) {
LOGGER.info("validCredentials(realm,
credential)");
return
CredentialValidationOutput.failed();
}
In the
UserFederationProvider interface i read that validCredentials
:
Validate credentials
of unknown user. The authenticated user is
recognized based on provided credentials and
returned back in CredentialValidationOutput
It seems to
be the method i was looking for just because
CredentialValidationOutput contains custom messages to be
sent as validation output. The problem is this method is
never called.
