If you are a user with total control permissions, you will have access to the account management features: delegating account management and merging accounts. Both options can be accessed from the Account management window (Preferences / Manage accounts).
This feature lets you delegate security management to a partner, or change the partner that takes care of managing your network security. For more information about this option, refer to the Delegating account management section.
When there are several client accounts, they can be merged to allow central management of the security of all computers. For more information about this option, refer to the Merging accounts section.
