We have recently been mandated to begin accounting for computer usage
based on CPU time.  Our situation is that we are running 4.3BSD on one
machine and Ultrix 2.0 (No source code) on a second machine.  Currently
we are using connect time to charge for computer usage.  This results
in a single user having multiple login names - one per chargable
project - for keeping track of connect time.  All logins for a given
user have the same UID/GID and there exists only one home directory for
each set of logins that a given user has.  It is somewhat inconvenient
for users in that they have to log off and back on (or use /bin/login)
to change projects.  However it is convenient in that most of our users
prefer having to manage only one set of directories.

The delivered UNIX software (sa) supports CPU time accounting using the
UID to identify the user.  This renders our current setup of using
multiple logins useless.  If we assign unique UIDs for each login, we
force users to have several home directories - something we would like
to avoid.  If we assign a common UID for each user's multiple logins,
but a unique GID, then this might help to solve our problem?  However
without adding an option to sa to use GID, we would have to sort the
information using a totally home grown program.  Also we cannot modify
system source since it is not available on our Ultrix host.  I would
appreciate any suggestions as to how we can implement an accounting
scheme which  supports multiple projects per user, and does not force
the user to maintain several home directories.
