Yes, ive tested the following:
AIX 4.3 Privsep on:		error
AIX 4.3 Privsep off:		ok
HP 11.0 privsep on or off:	ok
Linux privsep on or off:	ok

Working on the AIX privsep on case:
Putty (any version)		error
  tried 0.52, 0.53 and various development snapshots)
Cygwin's Openssh client		ok
SSH.COM client (3.2.2)		ok

I'll see if I can get gdb to follow that fork... so far I have had bad
luck following any fork :(

It happens after the password is entered, afaik just when normally the
shell should be exec'd on the unix side.
