[FreeNX-kNX] Backup strategy for Freenx

[G. Cazemier]

To all,

If I understand correctly, I cannot reinstall my server running Freenx 
without supplying a new client.id_dsa key to all users. This can be a 
problem because importing the key I supply them with is challenging 
enough for them...

So when I backup the contents of:
/var/lib/nxserver/nxhome/.ssh

And reinstall the server /completely/  (new keys are generated, I rename 
them for the sake of this experiment).
and I put back the keys from the backup my clients cannot connect.
I seem to have missed a step. But I cannot find a solution for this in 
the mailing list archives.

Thanks ,

GC
