Hi, again :)
I think you misunderstood our discussion.
The problem appears when two or more users have same fingerprint enrolled.
If we want pam_fprint module to identificate user, i.e. we want to login 
without entering username and password, only with swaping finger over sensor, 
we'll encounter problem in this case. So each user has to have its own 
fingerprint priority. If there's two users with same fingerprint(s) enrolled, 
pam_fprint module have to choose which one username to use for loging in, and 
it will choose user with higher priority, or will ask user for its username.

Regards
Vasily
