I tried to make a the /opt/apps folder accessible to all users of the 'www' group. The main user of the group would be the 'jboss' user, so I runned:
sudo chown -R jboss:www /opt/apps
Both the 'jboss' and the 'ubuntu' user are in the 'www' group, but only the 'jboss' user can write in the /opt/apps folder.
How can I make the /opt/apps folder writable to all users in the 'www' group?
