Yes, and yes, although I wouldn't recommend so if you have more than a
couple hundred users as that group will become enormous and will slow
down clients trying to fetch and cache all the memberships.

Having a common primary group is also often a security problem because
the default netmask on Linux machines is 220 meaning that all users can
read/write each other user' files by default if they all share the same
group.

To change the default primary group you can simply locate the
ipaDefaultPrimaryGroup attribute and change it from ipausers to whatever
you want to use.
