+Example Authentication Provider based on property file values
+=============================================================
+
+* To deploy copy "target/authentication-properties-example.jar" to "standalone/deployments/auth-server.war/WEB-INF/lib" . Then edit "standalone/configuration/keycloak-server.json" and add this:
+````shell
+    "authentication": {
+        "properties": {
+            "propertiesFileLocation": "users.properties"
+        }
+    }
+````
+
+* Then start (or restart)the server. Once started open the admin console, select your realm, then click on "Authentication" and then "Add provider" and select "properties" from the list.
+This will mean that realm will use PropertiesAuthenticationProvider for authentication.
+
+* Once you try to login to realm, you can login with username/password like "joe/password1" or "james/password2" . Once joe is authenticated,
+you can see in Keycloak admin console in "Users" list that user "joe" was added to the list.
+
+* You can try to login as joe and then go to [http://localhost:8080/auth/realms/keycloak-admin/account/password](http://localhost:8080/auth/realms/keycloak-admin/account/password) and change the password.
+You will then be able to logout and login with new password because properties were updated. But this is just in memory-properties, so after server restart the password will be again "password1" .
