Please remove (gnu services fingerprint) from your 'use-modules' form.
Sorry, I had asked you to add it, but it was a mistake from the manual,
which gives the wrong module name.

The correct module name is:

  (gnu services authentication)

which you can import by adding "authentication" to the
'use-service-modules' form.  This should fix the "unbound variable"
error.

In an earlier message you spoke of another error:

> but then new error regarding specifying values. :(

If you're still getting that error, can you show us the exact error
message and the configuration file that caused it?

     Regards,
       Mark
