## AuthDBGroupFile

Syntax: AuthDBGroupFile filename
Context: directory, .htaccess
Override: AuthConfig
Status: Extension
Module: mod_auth_db

The AuthDBGroupFile directive sets the name of a DB file containing the list of user groups for user authentication. Filename is the absolute path to the group file.

The group file is keyed on the username. The value for a user is a comma-separated list of the groups to which the users belongs. There must be no whitespace within the value, and it must never contain any colons.

Security: make sure that the AuthDBGroupFile is stored outside the document tree of the webserver; do not put it in the directory that it protects. Otherwise, clients will be able to download the AuthDBGroupFile.

## AuthDBUserFile

Syntax: AuthDBUserFile filename
Context: directory, .htaccess
Override: AuthConfig
Status: Extension
Module: mod_auth_db

The AuthDBUserFile directive sets the name of a DB file containing the list of users and passwords for user authentication. Filename is the absolute path to the user file.

The user file is keyed on the username. The value for a user is the crypt() encrypted password, optionally followed by a colon and arbitrary data. The colon and the data following it will be ignored by the server.

Security: make sure that the AuthDBUserFile is stored outside the document tree of the webserver; do not put it in the directory that it protects. Otherwise, clients will be able to download the AuthDBUserFile.
