The mod_authn_dbm Apache module provides the functionality for Apache to authenticate users with a database password file in the .dbm file format. This module works in conjunction with a front-end Apache authentication module. 


Use the mod_authn_dbm Apache module if you wish to use a database password file in the .dbm file format to authenticate users.


Front-end Apache authentication module

The mod_authn_dbm Apache module requires a front-end authentication Apache module. EasyApache includes the mod_auth_basic front-end Apache module by default.

For information on the mod_auth_basic Apache module, click the following links:

EasyApache can also provide the mod_auth_digest Apache front-end authentication module. For information on how to enable this module, read our Apache Module: AuthDigest documentation.

Database password file

To use the mod_authn_dbm Apache module, you must have a database password file in the .dbm file format.


This module has no known compatibility issues.
