Permissions have to be assigned to group of users so, after creating a user, you have to assign it to at least one group.
Otherwise, the user will not be allowed to do anything into Indyco Explorer.
If a user belongs to more than one group, than its resulting permission set will be the union of its groups' permissions:

You can assign a default set of privileges to a group: they will be applied to every project.
In case you need to override it for specific projects, you can activate the "Override" and enable / disable permissions for that project.
Some permission can also be restricted to specific macroareas and areas (see the permission glossary below).
