Emulab FAQ: Setting Up a New Emulab: How do I add users to arbitrary unix groups on boss/ops

To add a user to an arbitrary unix group on boss and ops (say, wheel or bin or operator) you need to add a entry to the database so that the Emulab account system knows about it. Editing /etc/group on boss and ops will not work since those changes will be removed by Emulab account system later. To permanently add someone to the wheel group:

	boss> withadminprivs /usr/testbed/sbin/unixgroups -a leebee wheel

Use the '-r' option to later remove a user from a group. To dump the current contents of the DB's auxiliary unix groups table, use the '-p' option.

Note that testbed administrators are automatically added to the wheel group on boss and ops.
