That helped me too. Thank you.
From 'man gshadow' I learned about the password field:
If the password field contains some string that is not a valid result of crypt(3), for instance ! or *, users will not be able to use a unix password to access the group (but group members do not need the password).
This field may be empty, in which case only the group members can gain the group permissions.
Presently, exclamation marks are in the password fields of gshadow. For the time being I'll leave it like that. Any comments?

==> Warning: /etc/group or /etc/gshadow are inconsistant.
Run 'grpck' to correct this.
After running sudo grpck I receive these messages
