I got openldap running as user db for samba, now I want to use it also as database for radius, I think it should be possible to use it without big modifications or?

Sure; odds are you probably won't need to write any code or even recompile. (What's a "big modification" anyway?)

You'd probably be best served by taking an example entry from your existing installation, and working with the FreeRADIUS docs/community to figure out the best architecture to integrate it. Once you have a plan, we can probably work with you on implementing the OpenLDAP side of the house, but I'm not sure if we can tell you how to configure a FreeRADIUS database.
