1PAM module for fingerprint authentication
2-----------------------------------------

4Using:
5* Modify the appropriate PAM configuration file
6(/etc/pam.d/system-auth-ac on Fedora systems), and add the line:
7auth sufficient pam_fprintd.so
8before the line:
9auth sufficient pam_unix.so ...
10* You can now enroll fingerprints using fprintd-enroll. The first available
11 fingerprint available will be used to log you in.
12
13Options:
14* You can add the "debug" option on the pam configuration file line above,
15 this will log more information from PAM to the file specified in your
16 syslog configuration (/var/log/secure by default on Fedora)

18Known issues:
19* pam_fprintd does not support identifying the user itself as
20 that would mean having the fingerprint reader on for all the time
21 the user selection is displayed, and could damage the hardware.
22 It could be fixed by having gdm/login only start the PAM conversation
23 when there is activity
24* pam_fprintd doesn't support entering either the password or a fingerprint,
25 as pam_thinkfinger does, because it's a gross hack, and could be fixed
26 by having the login managers run 2 separate PAM stacks
