Actions of an Active Directory service user within the Metasys system are controlled in the same manner as a Metasys local user, through assigned privileges. The data store for user privileges is a SQL Server database on computer/server platforms (Metasys server and SCT). For Active Directory service users, account policy settings – including maximum password age, account lockout, password uniqueness, and password complexity – are controlled outside of the Metasys system by the Active Directory service domain server. These settings are shaded when displayed in the Security Administrator System window. The Session Timeout attribute is one exception.
