Hi

Cryptfilters != Checkoutfilters.
(Take a look into lm_attr.h to find info about lc_set_attr values)

If you would have cryptfilters, you'd have to build lmkeyfil.c by yourself
as it is discribed in Nolans essay

If I remember correctly there's a tutorial about checkoutfilters at Crackz
site as well. Check it out again.

Greetings
