Description Massimo Burcheri 2006-02-19 04:56:10 UTC

cryptsetup-luks doesn't read properly from stdin. Therefore I can't get it working with pam_mount, which provides the key out of a ssl decrypted file.

Quite old report about the same problem:

This is a problem relating to reading from a FD and terminating with \0 or \n.
