The MashZone NextGen repository contains information on users and groups, authorization policies, server configuration, and much more.
User Data: for authentication and determining authorization.
Typically user data comes from your organization's LDAP directory which you integrate with MashZone NextGen. This may also use a single sign-on solution and an identity manager. However, MashZone NextGen also has a built-in user repository which you may use. User or group meta-data from LDAP allows MashZone NextGen to relate authorization policies with users.
