The Program users form lists the users who have individual rights to the selected program. Any rights users have because of the user groups they belong to are not displayed here. To see those rights, check the Program user groups form.
This form also allows you to grant one or more users rights to the selected program. To do so, add the user to the Program users form, and then assign permissions.
Isah allows you to grant rights in many ways, for instance to programs, users, or user groups. Regardless of how these rights were granted, they are all saved in the same file. Any rights added using the Program users form will therefore also appear on the User rights form.
