3.6.1 HP PolyServe Matrix Server Administration Guide (T5392-96018, August 2008)

Chapter 12: Configure Security Features 142
Matrix Server provides a built-in System Administrator role that includes
all members of the machine local Administrators group. This group has
permission to perform all matrix operations. In general, if a user in the
System Administrator role belongs to another role that denies a matrix
operation, the deny will override the permission granted to the System
Administrator role. However, members of the System Administrator role
always have permission to perform security operations, regardless of
their memberships in other roles.
Roles are configured on the Role-Based Security Control Panel. To open
the Control Panel, select Tools > Role-Based Security on the PolyServe
Management Console. The Control Panel lists all roles that have been
created. (The default System Administrator role is not included.)
