Apache 2.4 reverse proxy with digest authentication and macros

[Emanuele Bastianelli <manu.reeko@xxxxxxxxx>]

Hi,

I'm having a problem configuring Apache 2.4 as a reverse proxy with Digest Authentication. The strange behaviour is that if I activate the reverse proxy directives, the authentication stops working.

For design reasons, I'm using mod_macro. These are my config files:

macro.conf

<Macro RequestedURI $request_uri>

        <Location ~ "^$request_uri">

                AuthName $request_uri

                AuthType Digest

                AuthDigestAlgorithm MD5

                AuthDigestDomain /

                AuthDigestProvider dbd

                AuthDBDUserRealmQuery "SELECT password FROM password WHERE username = %s AND realm = %s"

                Require valid-user

                ProxyPass http://localhost:9000/$request_uri/

                ProxyPassReverse http://localhost:9000/$request_uri/

                Require all granted

        </Location>

</Macro>

000-default.conf

<VirtualHost *:80>

        ServerAdmin webmaster@localhost

        DocumentRoot /var/www/html

        ErrorLog ${APACHE_LOG_DIR}/error.log

        CustomLog ${APACHE_LOG_DIR}/access.log combined

        ProxyPreserveHost On

        RewriteEngine on

        DBDriver mysql

        DBDParams "host=localhost port=3306 user=myuser pass=mypass dbname=apacheauth"

        DBDMin  2

        DBDKeep 4

        DBDMax  10

        DBDExptime 300

        Use RequestedURI /test

        Use RequestedURI /othertest

</VirtualHost>

Without ProxyPreserveHost, RewriteEngine, ProxyPass and ProxyPassReverse, the authentication works perfectly.

Any hint?

Thanks in advance
