I just upgraded a 1.6K/i386 box to 1.6N of 11 Feb. ssh/telnet/ftp/rsh
from another host all let me login, but su/login on the same host don't.
What is the difference?! (I even since changed the passwords, and went from
old->md5 as old is still the default in libutil/passwd.c pw_default() but
have the same observation..) Oh, and this isn't just su root, su anything
gives iruserok failed.

Cheers,

Patrick
