The X2Go load balancing setup requires several installation steps.

1. Install more than one X2Go Servers
2. Install all X2Go Servers identically (FAI and/or puppet are good tools here)
3. Hook them together:
   • central LDAP server with user accounts as authentication backend and user base (PAM, libnss)
   • central NFS server for provisioning of home directories
   • make sure DNS works well and all X2Go Servers resolve and reverse resolve fine
4. Install PostgreSQL on a non-X2Go Server (i.e. on the machine that runs the LDAP service)
5. Hook all X2Go Servers' session databases into the PostgreSQL database server
