different PAM/ssh server-session sequences for root and regular users?

[Frank Mohr]

Hi

I just noticed different sequences of PAM/ssh-session calls.
(env: OpenSSH 3.8p1 on Linux with PAM-0.75)

The channel 0 (server-session) seems to be startet very early for root
and and after the pam-session is started for regular users.

As a result, regular users don't have a tty when the pam-session modules
are called.

Is this intended?

Frank
