Directory Services Data Structures
Directory Services holds and provides access to information about objects
(generally existing in telecommunications and information processing).
Directory Services stores information in an area collectively known as
the Directory Information Base (DIB).
FTAM uses Directory Services to identify responders. One analogy is
that Directory Services is like a telephone directory that lists responders.
For communicating with other systems and processes, you need to know
how to identify yourself and the systems and processes with which you
want to communicate. FTAM uses Directory Services to obtain the
presentation addresses (called_presentation_address) for such
identification purposes. To obtain these addresses, Directory Services
uses the directory distinguished names (called_dir_name,
source_dirname, destination_dirname, and dirname) that you provide.
For information on configuring your directory distinguished names and
presentation addresses for the OTS/9000 IEEE 802.3 link, refer to the
OSI Troubleshooting Guide.
Organizing Directory Services
The Directory Service organization starts at a root entry that is the base
for all entries. The following list provides possible entries in the required
order.
• Country
• Locality
• Organization
• Organizational Unit
• Application Process (AP)
• Application Entity (AE)
Figure 3-1 depicts one possible organizational structure of Directory
Services.
