+This will start a LDAP Server witch can be used to auth against and bridge the auth to where ever you want (TextFile, Database, SMTP Auth...)
+
+# HowTo Server
+Starting the Server is simple:
+```
+var ldapAuth = require('./ldapAuth');
+
+ldapAuth.init({
+  serverPort : 389, //Default 389
+	ldapServerPassword : "asdg", //Change password here
+	warningCallback : function(warning) {
+		console.log("warning",warning);
+	},
+	errorCallback : function(error) {
+		console.log("error",error);
+	},
+	checkPassword : function(auth, isPasswordCorrectCallback) {
+		var userName = auth["userName"];
+		var userPassword = auth["userPassword"];
+
+		if(userName=="test" && userPassword=="test") { //Test user+pw combination here
+			isPasswordCorrectCallback(true);
+		} else {
+			isPasswordCorrectCallback(false);
+		}
+	}
+});
+```
