Redmine

h1. Repositories access control with apache mod dav svn and mod perl

{{>TOC}}

h2. Overview

In this documentation, we will configure apache to delegate authentication to mod_perl. It's tested on apache2 with mysql and postgresql but should work with allmost every databases for which there is a perl DBD module.

You need Redmine r860 or later. If your Redmine is older than r916, download "Redmine.pm":http://redmine.rubyforge.org/svn/trunk/extra/svn/Redmine.pm

You need a working apache on your SVN server and you must install some modules at least mod_dav_svn, mod_perl2, DBI and DBD::mysql (or the DBD driver for you database as it should work on allmost all databases).

If the repositories are not created automatically by reposman.rb, it is important that the repository name is the same as the project identifier in Redmine, otherwise Redmine.pm will fail to authenticate users.

On Debian/ubuntu you must do :

  aptitude install libapache2-svn libapache-dbi-perl libapache2-mod-perl2 libdbd-mysql-perl libdigest-sha1-perl

h2. Enabling apache modules

On debian/ubuntu :

<pre>

a2enmod dav

a2enmod dav_svn

a2enmod perl

</pre>

h2. Apache configuration for subversion repositories and redmine 0.7.X and before

You need to copy "Redmine.pm" on your SVN server and add something like that to your apache configuration (for example in @/etc/APACHE_DIR/conf.d/@)

You must change the Redmine.pm path and database informations to fit your needs.

<pre>

   PerlRequire /usr/local/apache/Redmine.pm

   <Location /svn>

     DAV svn

     SVNParentPath "/var/svn"

     AuthType Basic

     AuthName redmine

     Require valid-user

     PerlAccessHandler Apache::Authn::Redmine::access_handler

     PerlAuthenHandler Apache::Authn::Redmine::authen_handler

     ## for mysql

     PerlSetVar dsn DBI:mysql:database=databasename;host=my.db.server

     ## for postgres

     # PerlSetVar dsn DBI:Pg:dbname=databasename;host=my.db.server

     PerlSetVar db_user redmine

     PerlSetVar db_pass password

  </Location>

  # a private location in read only mode to allow Redmine browsing

  <Location /svn-private>

    DAV svn

    SVNParentPath "/var/svn"

    Order deny,allow

    Deny from all

    # only allow reading orders

    <Limit GET PROPFIND OPTIONS REPORT>

      Allow from redmine.server.ip

    </Limit>

  </Location>

</pre>

It will add add two Location directives, one @/svn@ with authentication and access control against the Redmine database for users and one @/svn-private@ in read-only with IP limitation for Redmine browsing.

And that's done. You can try to browse some public repository with:

<pre>

svn ls http://my.svn.server/svn/myproject

</pre>

If you try to browse some non public repository, it will ask you a password.

h2. Apache configuration for subversion repositories and redmine after 0.7.X 

There's some difference in Redmine.pm so configuration is different. Everything else in the previous part works.

You first need to copy or link Redmine.pm to /usr/lib/perl5/Apache/Redmine.pm, then you add this configuration to apache :

<pre>

   PerlLoadModule Apache::Redmine

   <Location /svn>

     DAV svn

     SVNParentPath "/var/svn"

     AuthType Basic

     AuthName redmine

     Require valid-user

     PerlAccessHandler Apache::Authn::Redmine::access_handler

     PerlAuthenHandler Apache::Authn::Redmine::authen_handler

     ## for mysql

     RedmineDSN "DBI:mysql:database=databasename;host=my.db.server"

     ## for postgres

     # RedmineDSN "DBI:Pg:dbname=databasename;host=my.db.server"

     RedmineDbUser "redmine"

     RedmineDbPass "password"

  </Location>

</pre>

h2. Apache configuration for after redmine 0.7.X and git access

Now that reposman.rb can create git repositories, you can use Redmine.pm to access them the same way than subversion. You first need to copy or link Redmine.pm to /usr/lib/perl5/Apache/Redmine.pm, then you add this configuration to apache : 

<pre>

Alias /git /var/git

PerlLoadModule Apache::Redmine

<Location /git>

  DAV on

  AuthType Basic

  Require valid-user

  AuthName "Git"

  PerlAccessHandler Apache::Authn::Redmine::access_handler

  PerlAuthenHandler Apache::Authn::Redmine::authen_handler

  RedmineDSN "DBI:mysql:database=redmine;host=localhost"

  RedmineDbUser "redmine"

  RedmineDbPass "password"

</Location>

Alias /git-private /var/git

<Location /git-private>

   Order deny,allow

   Deny from all

   <Limit GET PROPFIND OPTIONS REPORT>

      Options Indexes FollowSymLinks MultiViews

   Allow from 127.0.0.1

   </Limit>

</Location>

</pre>

To verify that you can access repository through Redmine.pm, you can use curl :

<pre>

% curl --netrc --location http://localhost/git/ecookbook/HEAD   

ref: refs/heads/master

</pre>
