Is it possible to get the matched regex from within the apache LocationMatch directive?

  • 772

I'm wondering if the following code should be working:

<LocationMatch "/(.*)([/])?(.*)">
    Order allow,deny
    Allow from all

    AuthType Basic
    AuthName "Git"
    AuthUserFile  /git/.htpasswd
    AuthGroupFile /git/.htgroup
    Require group $1
</LocationMatch>

What I am trying to achieve with this is to require a group based on the first regex variable. So if the user goes to http://localhost/a-repository-name he has to be in the group a-repository-name to be able to open the url.

For some reason I can't get this code working and apache returns: Authorization of user **** to access /a-repository-name failed, reason: user is not part of the 'require'ed group(s).
I guess it's not matching against the proper variable at Require group $1.
Is this the right way to be done or I'm missing something?

  1. According to the Apache documentation this is now supported...

    From 2.4.8 onwards, named groups and backreferences are captured and written to the environment with the corresponding name prefixed with "MATCH_" and in upper case. This allows elements of URLs to be referenced from within expressions and modules like mod_rewrite. In order to prevent confusion, numbered (unnamed) backreferences are ignored. Use named groups instead.

    <LocationMatch "^/combined/(?<sitename>[^/]+)">
    require ldap-group cn=%{env:MATCH_SITENAME},ou=combined,o=Example
</LocationMatch>

    LocationMatch doesn't support backreferencing, you can't do that in versions before 2.4.8.
