Ok,
I'm transcripting the debugging information. First of all I have an
encripted "partition" for /home/casimiro that is mount via loop0. It was
working well until last update. It is still mounting when I use input lile:
# openssl aes-256-cbc -d -in /etc/pki/cryptofs/mykey.key | mount -p0 -o
loop,encryption=aes-cbc-256,rw /xxx/yyy.img /home/casimiro
But, when it goes to PAM... that's what happen:
