Thanks for all advises.
I actually don't need a full ssh implementation. The thing a wanted was a simple password-authentification for non-technical users without support for rsa-keys, remote execution etc.
But it sounds to complicated for a side-project...

Problem solved. Not quite the solution I hoped for but anyway...

regards,
jake
