Title:
User with passwords containing deadkeys may experience problems
logging in.
Status in lightdm package in Ubuntu:
New
Bug description:
I found a bug that leaves a users unable to log his account in a TTY.
the bug occurs when the user has its keyboard layout set to support deadkeys.
and chooses a password with a "^" character.
The graphics interface will not support deadkeys whereas the textmode login
(without lightdm) does.
What i expect to happen:
that it does not matter wich login i use, they will be consistent.
What actually happens:
So when a user graphicaly creates a password: "ab[shift-6]c" ([shift-6] is
the ^ char on my keyboard)
it will be intepretated as "ab^c" and when he uses the spacebar
"ab[shift-6][space]c" it is "ab^ c".
the problem is whatever you try to login in TTY it wont work.
the other way around is the same a password with the "^" created in
TTY wont be able to login in graphical.
