[Bug 70901] GDM doesn't allow login if password contains "é" character

[Pedro Menezes]

Public bug reported:

Binary package hint: gdm

If an account is defined with a password containing a "é" character:

- Login on a terminal -> Works
- Access through samba -> Works
- Access through SSH -> Works
- Login through GDM -> FAILS 

It fails as if the password was entered incorrectly.
It also maybe the case with other character (è,à, etc...)

Also if you have a password without this character and you add it at the
end of the password entry field (so it will be a wrong password
entered):

- Login on a terminal -> Fails
- Access through samba -> Fails
- Access through SSH -> Fails
- Login through GDM -> WORKS

So it looks like GDM has having issues processing the "é" character (or
skipping it all together).

I've seen a post about something very similar to this but it was deemed as not a GDM bug but rather a PAM bug:

But I don't think that it is a PAM bug because at least one of the other
methods (terminal login, samba access, SSH access) should also have this
issue if the problem was with PAM.

I'm using Ubuntu 6.06 LTS (Dapper) x86_64.
