Although there are additional administrative levels provided with the standard set of LMS Roles, only Portal Administrators have authority to both view, use, or edit most LMS features, master data, and configurations. Therefore, you typically only want to assign this role to key resources who oversee and manage all areas of the LMS.
As you manage any user account, remember that a user’s Profiles must contain at least one assignment to each of the following elements:
All users, including portal administrators must have an active profile at a Location. To grant a user full Portal Administrator rights, you must create a secondary profile tied to the Company level and assign it the highest managerial Position in addition to the Portal Administrator Role.
This is how the list of how the profiles should look for a company-wide portal administrator.
What happens next?
Once you make someone a Portal Administrator, you will not be able to impersonate that user. By design, Portal Administrators cannot impersonate others with the same level of access rights.
To get around this, some information about fellow portal administrators may be found on the My Team – People page.
