In most cases, the ACLs created by default for new servers should be adequate. In normal operation, the
only ACL that has to be altered is the one for the SSM client interface. This is handled automatically by
the -ssm option of the hpssuser utility. If, for some reason, an ACL should need to be modified in some
other way, the hpss_server_acl utility can be used. See the hpss_server_acl man page for more
information.
2.3. SSM User Security
SSM supports two types of users, administrators and operators:
• admin. This security level is normally assigned to an HPSS administrator. Administrators may
open all SSM windows and perform all control functions provided by SSM.
• operator. This security level is normally assigned to an HPSS operator. Operators may open
most SSM windows and can perform all SSM control functions except for HPSS configuration.
Security is applied both at the window level and the field level. A user must have permission to open a
window to do anything with it at all. If the user does succeed in opening a window, all items on that
window may be viewed. Field level security then determines whether the user can modify fields, push
buttons, or otherwise modify the window.
The security level of an SSM user is determined by his entry in the access control information table in
the HPSS configuration database. The initial security level for a user is assigned when the SSM user is
created by hpssuser. Security levels may be viewed and modified with the hpss_server_acl utility.
See also Section 3.3.2.2: SSM User Authorization on page 36.
2.4. Location Policy
All Location servers in an HPSS installation share a Location Policy. The Location Policy is used by the
Location Servers to determine how and how often information should be updated. In general, most of the
default values for the policy can be used without change.
