I had a similar issue when trying to debug a script that was trying to
perform a newgrp to the user's primary group.  It turned out the user
needed the group listed in his/her additional groups as well.

For example, do:
usermod -g foo -G foo,bar,baz example

rather than:
usermod -g foo -G bar,baz example

Hope this helps
