This sounds very interesting! But how does it work? Are the otps derived
from the user's key?

BTW: I solved this problem on my own (the tip with PAM was great). I wrote
a PAM module that creates the credentials by the use of a keytab file
after the user is authenticated (by the pam s/key module).

Thank you all.
