      1) Add user - add following line to standalone/configuration/mgmt-users.properties

      user1=pass@123

      2) Configure application server:

      /subsystem=elytron/sasl-authentication-factory=elytronSaslAuthnFactory:add(security-domain=ManagementDomain,sasl-server-factory=elytron,mechanism-configurations=[{mechanism-name=PLAIN}])
/subsystem=elytron/properties-realm=ManagementRealm:write-attribute(name=users-properties.plain-text,value=true)

      3) Change http-interface to following:

      <http-interface http-authentication-factory="management-http-authentication">
    <http-upgrade enabled="true" sasl-authentication-factory="elytronSaslAuthnFactory"/>
    <socket-binding http="management-http"/>
</http-interface>

      4) Run following code:

      AuthenticationConfiguration common = AuthenticationConfiguration.EMPTY
        .useProviders(() -> new Provider[] { new WildFlyElytronProvider() })
        .allowAllSaslMechanisms();

AuthenticationContext context = AuthenticationContext.empty();

AuthenticationConfiguration user = common.useName("user1").usePassword("pass@123");
context = context.with(MatchRule.ALL, user);

context.run(new Runnable() {

    @Override
    public void run() {
        try {
            ModelControllerClient client = ModelControllerClient.Factory
                    .create(new ModelControllerClientConfiguration.Builder()
                            .setHostName("127.0.0.1")
                            .setPort(9990)
                            .setConnectionTimeout(10000)
                            .build());

            ModelNode operation = new ModelNode();
            operation.get("operation").set("whoami");
            operation.get("verbose").set("true");

            System.out.println("Executing Operation\n");
            System.out.println(operation.toString());

            ModelNode result = client.execute(operation);

            System.out.println("\nResult\n");
            System.out.println(result.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
});

      It fails with exception mentioned in description.

      5) Remove WildFlyElytronProvider from useProviders of AuthenticationConfiguration and run again -> it passes correctly.

      In case when WildFlyElytronProvider is set as provider for AuthenticationConfiguration then SASL PLAIN mechanism is stopped to work (see exception below). In case when WildFlyElytronProvider is removed then PLAIN mechanism works. It seems that Elytron does not implement SASL PLAIN mechanism correctly.

      We request blocker flag because this issue blocks RFE EAP7-530. PLAIN is widely used SASL mechanism.
