The problem arises because if you check line 154 of bsd-login.c, OpenSSH
writes out a *utmp* record into utmpx.  (Along with a variety of other nasty
things, like opening the same file twice and not closing any of them, etc...)

I think somebody already mentioned this problem on the list, and submitted a

I avoided the problem by gutting login() to look like:

        struct utmp *utp;
        struct utmpx *utx;
        struct utmpx *old_utx;

        if((old_utx = pututxline(utx)) == NULL) {
                log("Could not update utmpx!");

        updwtmpx(_PATH_WTMPX, utx);

Obviously it destroys portability to other platforms, but it was just a quick
"make it go" fix.
