Description:

The module mod_authn_dbi provides Authentication against an SQL database
backend. It uses the application-independent abstraction layer provided by
libdbi. Database drivers for libdbi are provided by the libdbi-drivers,
project. At the moment, drivers are provided for MySQL, PostgreSQL, SQLite,
mSQL and FreeTDS (MSSQL/Sybase).

mod_authn_dbi is very flexible and offers several levels of customization. This
makes it easy to integrate it into existing installations and authenticate
users without having to alter the structure of existing tables. It is also
relatively easy to port existing authentication information from other sources,
e.g. file-based authentication to a backend for use by mod_authn_dbi.
