I don't really understand your mail - first you say that 
verification/pam_fprint works fine, then you say you can't get it to 
accept a fingerprint?

Anyway, if you're having false rejection issues, then you should look at 
the images and examine their appearance. Look for how smooth they are, 
how similar they appear, how much of the finger they cover. Also if you 
use fprint_demo you can ask it to plot the minutiae - see how good a job 
it does at that. Finally you can enable libfprint debugging and see the 
bozorth3 match scores for when it compares to the default threshold of 
40 (40+ = match).
