kr-cmds and dropping login.krb5 (was RE: Is anyone or a groupof people able to maintain appl/bsd betterthan MIT)

[Nicolas.Williams@ubsw.com]

BTW, my login.krb5 proposal argument is not too clean:

With SSHv2 /bin/login is not really appropriate for initial
authentication (i.e., password of keyboard-interactive); this
is because /bin/login needs a TTY and SSHv2 sessions can be had
without PTYs (or with PTYs channels started after other channel
types) and yet authentication must be performed before any
channel is allowed to be opened.

With klogind/telnetd this is not so and a PTY must always be
used so /bin/login is just fine thank you, as long as /bin/login
supports initial authentication through PAM+PAM_KRB5 or directly
supports Kerberos for initial authentication (are there SIA
plug-ins for Kerberos? I know little about SIA).

Sigh.

I'd like the option to configure klogind/telnetd to use
/bin/login on the platforms where that would fine (e.g., Solaris,
Linux distributions that support PAM, HP-UX 11.x, etc...) or
where replacing /bin/login with one derived from the
SimplePAMApps is possible/reasonable.

Cheers,

Nico
