Hi Urs
You just need to setup an LDAP connector (there is instruction in SCN or Marketplace already).
Next bit is to make the LDAP connector the primary data source (for the Maintain Data Sources) for Authentication and make the data sources configuratio set to yes so password is required. This will allow end users to login to the End User Login Screen with their network password.
I don't think there will be any difference with 10.1
In short, the detailed steps I wrote above pretty much cover all what you need to do except for the LDAP connector and switching authentication to yes.
