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

     Hi,

sorry I wasn't more clear.
The password of the main user set in the installation is something like:  abc1234
The password of another user set by adduser is something like: 12_abcdefgh
These passwords work with a console or ssh login.

With these passwords lightdm gives an error about "incorrect password ... "
The lightdm logfile says:
     [+731.48s] DEBUG: Authenticate result for user thisuser: Authentication failure

So for me lightdm doesn't work with simple passwords.
By the way, it started working when I made the passwords longer.

   Regards, Sietse
