8. Internationalization Considerations
All text string attributes defined in this document of syntax
[RFC2279], as required by [RFC2252].
A language tag [RFC3066] for all of the text string attributes
defined in this document is contained in the printer-natural-
language-configured attribute.
Therefore, all object classes defined in this document conform to the
"IETF Policy on Character Sets and Languages" [RFC2277].
9. Security Considerations
See [RFC2829] for detailed guidance on authentication methods for
LDAP. See [RFC2830] for detailed guidance of using TLS/1.0 [RFC2246]
to supply connection confidentiality and data integrity for LDAP
sessions.
As with any LDAP schema, it is important to protect specific entries
and attributes with the appropriate access control. It is
particularly important that only administrators can modify entries
defined in this LDAP printer schema. Otherwise, an LDAP client might
be fooled into diverting print service requests from the original
printer (or spooler) to a malicious intruder’s host system, thus
exposing the information in printed documents.
For additional security considerations of deploying printers in an
IPP environment, see Section 8 of [RFC2911].
