The Manage Users interface allows you to create Users in SI and assign them to User Groups with permissions that you choose. You can also create Mobile Users and Resources here. We are mixing around terminology here so here is an explanation:
User - a person granted the ability to log in/sign in to SI, a "user" of SI.
Resource - a person that can be assigned to Projects, Tasks, and Service Orders. You may or may not grant the ability to login to SI to a Resource.
Mobile User - a person granted the ability to log in/sign in to the Mobile Install website.
So, the logic statements here are: "Every User is a Resource, but not every Resource is a User" and "Not every User is a Mobile Install User and vice versa".
Each User needs login credentials to access functions/features of SI. You control what access each User has via User Group permissions.
You must be logged into an SI Client with a User assigned to the User Group "Administrators", or be in a User Group that has been granted permission to create Users, in order to do this.
You can create as many Users/Resources as you need, regardless of the number of SI licenses you have. Concurrent logins are what are determined by your number of SI licenses.
This is the Manage Users interface:
This form allows you to Add, Edit, Delete Users/Resources. Click here for details on creating Users/Resources.
This allows you to disconnect users from the SI Server when needed. This is rarely used but could be necessary if a user chooses to Work Offline and then their laptop dies/is stolen.
Note: Any user that is assigned to the Administrators User Group automatically will "bump" out another random User if they log in to SI.
You can manage your User Groups. User Groups are where you set permissions for your Users.
You can manage your Roles. This will open the Manage Roles form where you can add/edit/delete roles. Roles are designations for you Users/Resources that identify what they do.
Roles are used extensively on Workflow Rules to determine who to notify when a rule is triggered.
There are Report Settings that apply to Roles for use on custom Reports.
You can manage your User Sign-In Policies to set session logout and password preferences.
This section of the ribbon allows you to filter your Users.
Inactive users have a red X displayed in the Inactive column.
You can mark a user as inactive by checking the box when editing the user:
The Manage button in the Mobile Installer section of the ribbon allows you to Create/Map/Update/Invite Mobile Installers. Click here for details.
