The User Management feature facilitates the creation and management of users and their roles, category-based permissions, and privileges. Administrators can create and manage user details for Metasys local and external users. From Metasys Release 14.0, external OAuth authentication is available along with Active Directory over LDAP and LDAPS. External OAuth authentication helps to prevent unauthorized access to Metasys, which, if not prevented, could result in data, financial, and reputation loss, system disruption, and other negative consequences.
