Groups
Administrators can designate up to 32 groups to be used in association with either the Internal accounts or LDAP/LDAP
+GSSAPI building blocks. To ensure device security, groups are used to identify sets of users needing access to similar
functions. For example, in Company A, employees in the warehouse do not need to print in color, but employees in
sales and marketing use color every day. In this scenario, you can create a “Warehouse” group and a “Sales and
Marketing” group.
Access Controls
By default, all device menus, settings, and functions come with no security enabled. Access controls (also referred to
in some devices as “Function Access Controls”) are used to manage access to specific menus and functions or to disable
them entirely. Access controls can be set using a password, PIN, or security template. The number of functions that
can be controlled varies depending on the type of device, but in some multifunction printers, over 40 individual menus
and functions can be protected.
Note: For a list of individual access controls and what they do, see
“Appendix C: Access controls” on page 66.
Security Templates
Some scenarios call for only limited security, such as PINprotected access to common device functions, while others
require tighter security and rolebased restrictions. Individually, building blocks, groups, and access controls may not
meet the needs of a complex security environment. In order to accommodate users in different groups needing access
to a common set of functions such as printing, copying, and faxing, administrators must be able to combine these
components in ways that give all users the functions they need, while restricting other functions to only authorized
users.
A security template is a profile constructed using a building block, or certain building blocks paired with one or more
groups. How they are combined determines the type of security created:
Building block Type of security
Internal Accounts Authentication only
Internal Accounts with Groups Authentication and authorization
Kerberos 5 Authentication only
LDAP Authentication only
LDAP with Groups Authentication and authorization
LDAP+GSSAPI Authentication only
LDAP+GSSAPI with Groups Authentication and authorization
Password Authorization only
PIN Authorization only
Each device can support up to 140 security templates, allowing administrators to create very specific profiles for each
access control.
Accessing the Embedded Web Server
