            | Issue | In QNX 4.25 when we attempt to use the 'newgrp' command to change to a secondary group we get a message saying I'm not a member of the group and get logged off the shell.  How do we ourselfs part of two groups?

            | Solution | The user must be added to the secondary group in the etc/group file (as the superuser). 
 'newgrp' is used to switch between the groups but it is looking at the etc/group to see if the user is a member of the secondary group.
 
 For further details, see /etc/group in the 'Setting Up User Accounts' chapter of the QNX OS Installation and Configuration Manual.
