[keycloak-user] Custom password hash provider seems not getting triggered

Hi, I've implemented a custom user storage provider and a custom password hash provider as the user storage doesn't use Pbkdf2. I added some logging to check if I can see it in the server.log but there's no output from my custom password hash provider: public class MyPasswordHashProvider implements PasswordHashProviderFactory, PasswordHashProvider { private static final Logger logger = Logger.getLogger(MyPasswordHashProvider.class); public static final String ID = "XX"; public PasswordHashProvider create(KeycloakSession session) { logger.info(">>>>>> Creating factory"); return this; } public void close() { logger.info("<<<<<< Closing provider/factory"); } public void encode(String rawPassword, PasswordPolicy policy, CredentialModel credential) { logger.info("Encoding password"); String salt = getSalt(); String encodedPassword = encode(rawPassword, salt); credential.setType(UserCredentialModel.PASSWORD); credential.setValue(encodedPassword); credential.setSalt(salt.getBytes()); credential.setAlgorithm(ID); logger.info("Credential model: " + credential); } } In src/main/resources/META-INF/services I've created a file called org.keycloak.credential.hash.PasswordHashProviderFactory which contains the fully qualified class name (including package): com.example.keycloak.credential.hash.MyPasswordHashProvider This is the log I can see while trying to login: 2017-03-14 14:57:14,215 INFO [com.example.keycloak.storage.MyUserStorageProviderFactory] (default task-4) >>>>>> Creating factory 2017-03-14 14:57:14,217 WARN [org.keycloak.events] (default task-4) type=LOGIN_ERROR, realmId=test, clientId=test, userId=f:dbXXXXbb-aXXf-XXXX-befb-XXXeaXcbXXbb:john.doe@example.com, ipAddress=127.0.0.1, error=invalid_user_credentials, auth_method=openid-connect, auth_type=code, redirect_uri=https://XXX.XXX.XX.XX:8443/login.html, code_id=fbfXbXXX-dfdX-Xfba-bfXX-XXXXacXXXeXe, username=john.doe(a)example.com Do I miss something?
