Installation/authentication/authorization steps in subversion

Installing Subversion

• Execute the command sudo apt-get install subversion  libapache2-svn
  (libapache2-svn package contains: mod_dav_svn,mod_dav_auth to apache 2.2 webserver for dav access over http and https using webdav)

    Creation of repository

• After the subversion installation is completed we need to create repository
• svnadmin create /home/svn
• Once the repository creation is completed copy the file mod_dav_svn and mod_dav_auth from the location : c:\svn\bin\mod_dav_svn & c:\svn\bin\mod_dav_auth to c:\program files\apache software foundatino\apache2.2\module

Enabling http access

• open the file c:\program files\apache group\apache2\conf\httpd.conf in one of the editor
• Enabling Authenticationto enable authentication we need to add following  entries in the file mod_dav_svn.conf
• authtype basic means it will ask for username and password while login and it will get the authenticated users from the file AuthuserFile /opt/share/svn/svn-auth-file

AuthType Basic using this whenever we will hit the svn url it will ask for ususername/password: 

<Location /svn>
  DAV svn
  SVNListParentPath on
  SVNParentPath D:\SVN
  #SVNIndexXSLT "/svnindex.xsl"
  AuthType Basic
  AuthName "Subversion repositories"
  AuthUserFile passwd
  AuthzSVNAccessFile svnaccessfile
  Require valid-user
</Location>

Enabling Authorization
To enable path based authorization for svn repository we need to uncomment  the line AuthzSVNAccessFile svnaccessfile and
below is the sample of svnaccessfile for path based authorization   for svn repository.
