password restrictions are different in the GUI and on the command line.

PS: For some users I have no need for a password at all, so those user's
passwords are not nearly that strong, as the above mentioned passwords.
Sometimes it makes sense to set up a dummy user for testing purpose.
Consider to do the same and chose a really weak and short password and
if lightdm doesn't allow to log in, post the message, log file or what
ever else you get, saying that your password isn't strong enough.
