| Status: | Extension |
| Module Identifier: | authn_dbd_module |
| Source File: | mod_authn_dbd.c |
| Compatibility: | Available in Apache 2.1 and later |
This module provides authentication front-ends such as
mod_auth_digest and mod_auth_basic
to authenticate users by looking up users in SQL tables.
Similar functionality is provided by, for example,
mod_authn_file.
This module relies on mod_dbd to specify
the backend database driver and connection parameters, and
manage the database connections.
When using mod_auth_basic or
mod_auth_digest, this module is invoked via the
AuthBasicProvider or
AuthDigestProvider
with the dbd value.
This simple example shows use of this module in the context of the Authentication and DBD frameworks.
