The User Administrator:

• Creates (or imports) SPP users.
• Creates user groups.
• Grants Help Desk Administrator permissions to users.
• Sets passwords, unlocks users, and enables or disables non-administrator user accounts.
• Also has Help Desk Administrator permissions.

Considerations: 

• User Administrators cannot modify administrator passwords, including their own.
• User Administrators can change the permissions for their own account, which may affect their ability to grant Help Desk Administrator permissions to other users. When you make changes to your own permissions, they take effect next time you log in.
