Apache::AuthzSplitDomainUser - mod_perl module for checking the htgroup file while allowing you to manipulate with perl


    <Directory /foo/bar>
    # Optional Variables
    PerlSetVar groupFile /path/to/htgroups
    # Set the format of the username to check against
    # defaults to username
    PerlSetVar authzUsername username or domain\username

    PerlAuthzHandler Apache::AuthzSplitDomainUser

    # Standard require stuff, only user and 
    # valid-user work currently
    require valid-user

    # Optional, reqires that you have Apache::Htgroup
    # require group groupname

    These directives can be used in a .htaccess file as well.

    If you wish to use your own PerlAuthzHandler then the require 
    directive should follow whatever handler you use.


This module was written so that we could hijack the Authz phase from Apache and modify values that are passed to the Authz Handler with perl. The initial concept was to deal with a problem that we are seeing from winXP boxes that are sending forward DOMAIN\username to Apache. These obviously fail when checked against an authentication, or authorization, scheme where the syntax is simply username.

= item PerlSetVar groupFile

Set this to the path of the htgroup file you wish this module to check in. It allows you to specify your users in groups found on the web server, as opposed to groups within Active Directory, etc.

= item PerlSetVar authzUsername

Set this to "username" or "domain\username" depending on your preference. (This simply formats the input username to allowing checking the username as "domain\username" or "username".) For example:

# speeves is a DOMAIN user of DOMAIN domain\username => DOMAIN\speeves

# speeves is a DOMAIN user of DOMAIN, # but the server administrator wants to # check this user against groups in the # htgroup file as:

# groupname: speeves userA userB

username => speeves

If you allow users to use Domain\Username and restrict access using the require user username or require group groupname make sure to set the username with the domain included. The authorization phase will be looking for Domain\Username string.

Example: require user mydomain\ramirezc


If you are using this module please let me know, I'm curious how many people there are that need this type of functionality.
