NATS4 MySQL Auth
MySQL Auth is a feature supported by NATS that allows you to authenticate members against an external MySQL database. This is useful for clients who use an external member database to store information.
Setting up MySQL Auth
This article applies to mod_auth_mysql 3.0
Biller Member Management
In order to use the MySQL Auth feature, you must first tell the biller to turn off user management on their end.
.htaccess
For NATS password management, you will have to use a MySQL auth method, such as Apache's mod_auth_mysql. The following code consists of specific configuration settings for mod_auth_mysql:
AuthMYSQLEnable on AuthName "Members Only" AuthType Basic AuthGroupFile /dev/null AuthMySQLHost localhost AuthMySQLDB <name of the nats datatbase> AuthMySQLUser <user for the nats database> AuthMySQLPassword <password for the user for the nats database> AuthMySQLUserTable member_auth AuthMySQLNameField username AuthMySQLPasswordField password AuthMySQLPwEncryption none AuthMySQLUserCondition "siteid=X AND username != '' AND password != ''" require valid-user
Replace X in "siteid=X" with the ID number of the site you would like to affect. If you would like to use a single member's area for all of your sites, simply remove "AND siteid=X" from the line. For more options and information, please see our Multisite Access article. The NOT condition will prevent anyone from logging in without a username or password.
If you would like to use your old password files in combination with the mod_auth_mysql feature, simply add the following line to your configuration file on top of the auth mod_auth_mysql lines:
AuthMySQLAuthoritative Off
Notes
If other sites on the server use htaccess for authentication, but aren't using mod_auth_mysql, add the following options to the top of their htaccess files:
AuthMySQLEnable Off AuthMySQLAuthoritative Off
Alternate Server Member Management
If your NATS database is on a different server from your site member's area, use the following instructions to use MySQL Auth:
Use the GRANT command to give appropriate permissions to the NATS database username at the IP address of each member's area server. When this is done, change the value of the AuthMySQLHost directive to the IP address of the NATS server.
If you do not know how to do this, please request that your Host or Server admin allows the NATS database user to access the database from your member's area servers.
