How to use a RELATIVE path with AuthUserFile in htaccess?

Question

I have a .htaccess that uses basic authentication. It seems the path to the .htpasswd file isn't relative to the htaccess file, but instead to the server config.

So even though I have the .htaccess and .htpasswd files in the same directory, this doesn't work:

AuthType Basic AuthName "Private Login" AuthUserFile .htpasswd Require valid-user 

However, it does work if I change the AuthUserFile to use the absolute path:

AuthType Basic AuthName "Private Login" AuthUserFile "/home/user/public_html/mydir/.htpasswd" Require valid-user 

But I would prefer something more mobile as I use this on multiple sites in different areas. I've searched the web but haven't had any resolution. Is it possible to use relative path or variables like %{DOCUMENT_ROOT}?

Answer 1

It is not possible to use relative paths for AuthUserFile:

File-path is the path to the user file. If it is not absolute (i.e., if it doesn't begin with a slash), it is treated as relative to the ServerRoot.

You have to accept and work around that limitation.

We're using IfDefine together with an apache2 command line parameter:

.htaccess (suitable for both development and live systems):

<IfDefine !development>   AuthType Basic   AuthName "Say the secret word"   AuthUserFile /var/www/hostname/.htpasswd   Require valid-user </IfDefine> 

Development server configuration (Debian)

Append the following to /etc/apache2/envvars:

export APACHE_ARGUMENTS=-Ddevelopment 

Restart your apache afterwards and you'll get a password prompt only when you're not on the development server.

You can of course add another IfDefine for the development server, just copy the block and remove the !.
