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

there might be a GUI available to add a user, resp. to chose a
password and this GUI might recommend or even enforce to chose a more
secure password, but I doubt that lightdm doesn't work with a simple
password such as "cat1234", "dog5678" or "12345678", when such a less
secure password was chosen by command line.

How did you notice that lightdm doesn't work with a simple
password, chosen by command line? Did you get a message? Is there an
entry in the log file saying this?

You did not enter your simple password, while by accident caps lock was
active or something like this?
