Apache Module mod_authn_file

Available Languages:  en  |

 ja  |

Description:User authentication using text files
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 plain text password files.
    Similar functionality is provided by mod_authn_dbm.

    When using mod_auth_basic or
    mod_auth_digest, this module is invoked via the
    AuthBasicProvider or
    with the file value.

Password Formats

AuthUserFile Directive

Description:Sets the name of a text file containing the list of users and
passwords for authentication
Syntax:AuthUserFile file-path
Context:directory, .htaccess

    The AuthUserFile directive sets the name
    of a textual file containing the list of users and passwords for
    user authentication. File-path is the path to the user
    file. If it is not absolute, it is treated as relative to the

    Each line of the user file contains a username followed by
    a colon, followed by the encrypted password. If the same user
    ID is defined multiple times, mod_authn_file will
    use the first occurrence to verify the password.

    The encrypted password format depends on which authentication
    frontend (e.g. mod_auth_basic or
    mod_auth_digest) is being used.  See Password Formats for
    more information.

    For mod_auth_basic, use the utility htpasswd
    which is installed as part of the binary distribution, or which
    can be found in src/support. See the
    man page for more details.
    In short:

    Create a password file Filename with
    username as the initial ID. It will prompt for
    the password:

      htpasswd -c Filename username

    Add or modify username2 in the password file

      htpasswd Filename username2

    Note that searching large text files is very
    inefficient; AuthDBMUserFile should be used

    For mod_auth_digest, use htdigest
    instead. Note that you cannot mix user data for Digest Authentication
    and Basic Authentication within the same file.

      Make sure that the AuthUserFile is
      stored outside the document tree of the web-server. Do
      not put it in the directory that it protects.
      Otherwise, clients may be able to download the
