Description roger 1999-11-03 19:02:48 EST

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

Comment 1 Jeff Johnson 1999-11-05 08:12:59 EST

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.
