A plugin that allows the use of an external MySQL, PostgreSQL, or MSSQL database for authentication into wordpress. It requires you know the encryption method for the passwords stored in the external database and allows you to use MD5, SHA1, plaintext, or enter the hash/salt method yourself. It disables password reset/retrieval and account creation within the wordpress system on the user-end, and it doesn’t allow updating from the wordpress end back into the external authentication source. In addition to authentication the plugin allows you to: 1. Choose additional fields, such as first name/last name and website, to be imported into the wordpress user system. 1. Enter a custom message for users concerning logins. 1. Do user role checks from the external database: you can set the plugin to check from a specific role field and compare to a value to allow login to wordpress. PostgreSQL or MSSQL database authentication requires MDB2 PEAR database abstraction package and relevant database drivers. MySQL continues to use the built-in PHP functions.
