Description roger 1999-11-04 00:02:48 UTC

entering "exec login <username>" gives the usual password
prompt, but fails when the password is entered. The log file
shows
lynx login: setuid() failed

If the <username> is root, then the command is successful,
after entering the correct root password, but there is a
message
  No directory /root!
  Logging in with home = "/".he message

It appears that the login command is not executing setfsuid

Unlike many other programs (and many other unices), login is
responsible for preserving the PAM session. This is done by
an extra fork. Working out the pokery-jiggery necessary to
permit
	exec login ...
and
	login ...
to function "normally" is not worth the effort.
