Access role assignments for bus security resources
Icons are used in the admin console to represent users and groups that have access roles for service integration bus resources.
Security access roles
In the admin console, access role icons are used to represent whether a user or a group is in a particular access role. We can click an icon to add or remove selected users and groups to a particular access role for a selected resource.
An access role icon has three states:
- Access role type set.
- Access role type not set.
- Access role type inherited from group.
The following table describes how the access role icons represent these states, and how to change between them:
| Access role icon | Access role assignment state | User action |
|---|---|---|
 | Role type not set. | Click to change to role type set  .
|
| | Role type set. | Click to change to role type not set. The icon changes to role type not set if the user or group does not inherit access roles, or to role type inherited  if the role type does inherit access roles.
|
| | Role type inherited from group. | Click to change to role type set .
|
 | Role type not set for a group. The group to which a user belongs does not have a role type. | Read only. |
 | Role type set for a group. The group to which a user belongs has a role type. | Read only. |
 | Role type not applicable. | Read only. |
