How to authenticate SMPP server users with a database

When you operate your own SMS service, you might want to store user information in your database server. This user information can be used to authenticate users who are trying to access your server through various channels. For example you may authenticate SMPP client connections, HTTP API connections, UCP or CIMD2 SMS clients with the same user database. This guide gives you step by step instructions on how setup database user authentition for an SMPP server configuration. The steps are similar for other service channels you may setup. You can use Microsoft SQL Server, MySQL, Oracle, or any other database server.

Overview

If you store your SMPP SMS Server user information in a database table, you need to follow these steps in order to configure Ozeki 10 SMS gateway to query your database when an SMPP client tries to connect to decide whether he is authorized to use your service

  • Open the control panel
  • Create a database connection
  • Choose SQL queries
  • Select the databaser type
  • Enter the database login details
  • Create a new authentication provider
  • Write the SQL SELECT query to verify the user
  • Open the SMS Gateway app
  • Click Advanced on the toolbar
  • Select the SMPP server configuration
  • Open the advanced tab
  • Select the database authentication provider

Step 1 - Create Database Connection in Ozeki SMS Gateway

The first step is to open the Control Panel application in Ozeki SMS Gateway. So, just navigate to the desktop of Ozeki SMS Gateway, and here, as you can see it in Figure 1, just open Control Panel by clicking on its icon.

Now you should be on the Control Panel main page where you can create, modify or delete connections. Click on the blue Create new connection button and select Application from the box appearing on the right side of the screen (Figure 2).

In this example we will use MySQL Database to store the user details for the Authentication Provider. So select the MySQL connection type as the Figure 3-5 shows.

Then please fill out the following form with connection details. Make sure to provide the SQL server IP and port number. The default SQL port number is usually 3306. You also need to provide the name of the database where your users are. Finally provide the SQL username and password and click 'OK' (Figure 6).

Finally the connection was successful as you can see it on Figure 7.

Step 2 - Connect Database Authentication Provider to the SQL database

In this step we will set a SELECT query on the SQL table. This SELECT query will be called when a login attempt occurs. It checks the user table for users. Jump to the authentication provider page by clicking Authentication providers in the Users menu (Figure 8).

Figure 8 - Open Authentication providers menu

On the Authentication provider page you can create, modify or delete authentication providers. Create a new authentication provider by clicking the blue Create new authentication provider button. A new box will open on the right side of the page. In this box you can select between authentication providers. Please choose Database authentication provider (Figure 9).

A form will be available in the box. You should fill out the form to configure the database authentication provider. In the most important field you need to write the SQL query as you can see it in Figure 10. In STEP 4 we will set up an SQL database that is compatible with this SQL query.

SELECT * FROM user WHERE
Password = MD5("${password}") /* Hashes password and compares the hash. */
and User="${username}";

Step 3 - Create SMPP Service with SQL Authentication

The next step is to open the SMS Gateway application. So, just navigate to the desktop of, and here just open SMS Gateway by clicking on its icon. Here you can find the Advanced menu of the SMS Gateway. To open it please click the "Advanced" button on the main page.

On the Advanced page you can create, modify or delete SMS Services. Create a new SMS Services by clicking the blue Create new Service button. A new box will open on the right side of the page. In this box you can select between SMS Services as you can see in the Figure 12. And then please choose SMPP Service (Figure 13).

A form will be available in the box. You should fill out the form to configure the SMPP Service. Please provide a unique name and a port for this service as you can see it in Figure 14.

Then on the Advanced tab of the SMPP Service set the Database authentication provider in the User Authentication section as the Figure 15 shows.

Step 4 - Create SQL database table for users

To use the Database Authentication Provider you will need to have at least one SQL table that contains login information of the users. The table must have at least 2 columns. 1 column is for the username and the other one is for the password hash of the user's password. Now you will need to create a table in the database:
CREATE TABLE user (
    User VARCHAR(255),
    Password VARCHAR(255)
    );

create user table in database
Figure 16 - Create User table in database

Add user credentials to your table. You can use this table later on for user authentication. Ozeki SMS Gateway will search users in this table. Do not forget to hash the passwords as you can see below:
INSERT INTO user (User, Password)
VALUES ("Ozeki", MD5('123451')),
	   ("smppuser", MD5("qwe123"));

create users in database
Figure 17 - Create users in database

Finally if an SMPP Client is connecting with the username and password you created in the database, you will see that the User is appear in the SMS Gateway Users and applications section (Figure 18).
