How to give Dolibarr access to a member

I have configures Dolibarr inside my localhost as a super admin. Now I would like to give access to a member that I have created using the Dolibarr ERP. How can I do that. As you can see in the I have created two members.

As an example, when I select a user I can see that user has no Dolibarr access like in the .

Then I tried to validate that user by selecting “Validate” button and it gives me a pop-up like this

.

When I select the “Yes” option in the pop up dialog, I get an error message like this .

So, how can I validate a user and give him/her a separate login to this system ?
