Since 386/ix Version 2.0 crypted passwords are moved into an extra file,
named /etc/shadow, which is readable only by root. The /etc/passwd file
now contains only an `x' in its password column.
The TELNET protocol server (telnetd) seems to use /etc/netlogin when
creating a login process, which has never heard of /etc/shadow. I solved
that problem by copying the password column from /etc/shadow into
/etc/passwd. Telnet works fine since then, but the security improvement
is gone, it's a lot of unnecessary work and password changes must be
maintained by hand. Therefore this is not an optimal solution. Any hints?
