I want the users of the workstation to be able to get to the Change Password
dialogue so that they can change their individual passwords. If I set the
"user cannot change password" flag then the dialogue is not even accessible.
All I want to do is change the default value in the "User name" field so that
they don't carelessly keep banging on the auto login account when they are
really trying to change their own password.
For example, the way it works now is:
1) Workstation auto logs in as "Autouser"
2) "User1" starts App1 and provides his Windows user/password to App1 for
authorization.
3) "User2" signs "User1" out of App1 and provides his Windows user/password
to App1 for authorization.
4) "User1" decides to change his password, so he presses Ctrl-Alt-Del and
clicks the Change Password button. At that point, the Change Password
dialogue has the value "Autouser" in the "User name" field.
5) "User1" clicks on the "User name" field and replaces the value "Autouser"
with the value "User1", then proceeds to change his own password.
If "User1" does not do step 5 correctly, he is inadvertently trying to
change the "Autouser" password, or if he has obtained the password then he
can change the "Autouser" password. If I could simply clear the user field
we can avoid a lot of confusion.
