When users first register, their status is set to Requested. While a user's status is Requested, they will not be able to log in. Approving new users, and thereby allowing them  to log in, simply means changing their status to Normal. Deny the user request by changing their status to Denied or delete the user. It is also useful to define the users roles at this point. A new user can be assigned any role the person doing the assigning has. User approval can be done in the following places:

 

The User Requests page shows just the users whose status is Requested. It also provides short-cuts to approving or denying user requests and allows for user detail modification.
 

Modifying Users describes how to use the other options for modifying users. That is, the User Search page and the Data Explorer.
 

By default, Calpendo has an Automatic Email configured that will tell all administrators when there is a new user request. The email received contains links to approve or deny the new user request. Just click on the links in the email to approve or deny new users.

 

Please note that if a resource requires a project to be entered when a booking is made, a user cannot book that resource unless they are assigned to the project being used to make the booking.
