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

[Danny Trunk]

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

task-4) >>>>>> Creating factory

Do I miss something?
