At least on Linux Debian, vlock is compiled with PAM support:
dardhal:/tmp$ ldd vlock
libdl.so.2 => /lib/libdl.so.2 (0x4001d000)
libpam.so.0 => /lib/libpam.so.0 (0x40021000)
libpam_misc.so.0 => /lib/libpam_misc.so.0 (0x40029000)
libc.so.6 => /lib/libc.so.6 (0x4002c000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x40150000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
So there is a file under /etc/pam.d/ that includes authentication
configuration for vlock itself. Maybe the file is not configured
correctly. For example, in my installation it just has:
#%PAM-1.0
auth required pam_unix.so
Component "auth" for other PAMified programs such as login have the same
configuration under their respective file in /etc/pam.d. For more
information, check PAM documentation (/usr/share/doc/libpam-doc under
Debian, package libpam-doc).
Hope this helps.
