4. INSTALLATION

   You have to install openvpn first on your server. It needs openvpn-auth-pam.so in the openvpn directory. It can be find in the resource directory. For Debian you may use the following command:

     cp /usr/lib/openvpn/openvpn-auth-pam.so /etc/openvpn/
   

   pam-mysql needs to be installed. For Debian, use the following command to install it:

     aptitude install libpam-dev libpam-mysql libmysql++-dev sasl2-bin
   

   Also, you need to config pam-mysql. Add the following TWO lines in to '/etc/pam.d/openvpn'. If it doesn't exist, just create a new file:

     auth optional pam_mysql.so user=openvpn passwd=PASSWORD host=localhost db=openvpn table=user usercolumn=username passwdcolumn=password where=active=1 crypt=2
     account required pam_mysql.so user=openvpn passwd=PASSWORD host=localhost db=openvpn table=user usercolumn=username passwdcolumn=password where=active=1 crypt=2
   

   Remember to change the user, passwd, host and db according your database.

   Run

           saslauthd -a pam
   

   to start sasl authrization service.

   In your server.conf:

     Add   
   
           # user/pass auth from mysql
           plugin ./openvpn-auth-pam.so openvpn
           client-cert-not-required
           username-as-common-name
           
           # record in database
           script-security 2
           client-connect ./connect.sh
           client-disconnect ./disconnect.sh
   

   In your client.conf

     Comment out
   
           cert client.crt
           key client.key
   
     Add
   
           auth-user-pass
   

   If any part of the above code is already in your configuration file, don't just add it, but modify the existing config to above.

   Copy connect.sh and disconnect.sh from Script directory to the directory where OpenVPN is installed. /etc/openvpn for Debian.

   The user runs openvpn process needs to have executing permission on connect.sh and disconnect.sh. You need to change the database connection information in connect.sh and disconnect.sh
