[fprint] Experiences with libfprint in multi user environments

Hello Martin

Please let us know how it will work. You wrote you need identification, so
verification (ready to use fprintd-enroll and then fprintd-verify) will not
help you / will not enoug for you.

I'm also searching for sollution where only fingerprint is needed (no
keyboard needed, no user name berofe scanning is needed. I think it could
be called pfrintd-identify.

Please let me know if you will have some results.

Best regards
