That's not what the chuser info page on our system says.
It says:
	 login  Indicates whether the user specified by the Name parameter ca
     log into the system with the login command.  Possible values are:

         yes  The user can log into the system.  You can substitute the true
     keyword or the always keyword for the yes keyword.

         no  The user cannot log into the system. You can substitute the fals
		      ^^^^^^^^^^^^^^^
     keyword or the never keyword for the no keyword.

(Note the missing characters at the end of the line. I always get that
 when printing from InfoExplorer. Don't you?)

It is executed on our system. You get the login: prompt, and if you type the
user id of the user with "login=false", it still logs in, without
prompting for a password, because that was empty.
If you login on the serial tty, it WILL prompt you for a password,
and whatever you type, you're never logged in.
That's the way it should be via telnet and rlogin as well.

No, they don't, because they will prevent a user that IS logged in from
using these commands.
