[ltp] thinkfinger pam module doesn't allow ssh login

[Micha Feigin]

After some headaches I just discovered that enabling fingerprint logins using
the thinkfinger pam module doesn't allow users with a fingerprint to login
using ssh. The ssh connection just closes on attempted authentications with no
entry in /var/log/auth.log. Users with no fingerprint can login fine (dirty
workaround). Any ideas if I'm doing something wrong or if this is a bug with
the thinkfinger pam module?

The settings in /etc/pam.d/common-auth

auth    sufficient	pam_thinkfinger.so
auth	required	pam_unix.so try_first_pass nullok_secure

Thanks
