RFC 2164 X.500/LDAP Directory to Support MIXER January 1998
o It is the "natural" location, and will also help to
ensure correct administrative authority for a mapping
definition.
o The tree will usually be accessed for routing, and so it
will be efficient for addresses which are being routed.
This is not done, as the benefits of the approach proposed are
greater.
MCGAMs are global. A MIXER gateway may use any set of MCGAMs. A key
use of the directory is to enable MIXER gateways to share MCGAMs and
to share the effort of maintaining and publishing MCGAMs. This
specification and MIXER also recognise that there is not a single
unique location for publication of all MCGAMs. This specification
allows for multiple sets of MCGAMs to be published. Each set of
MCGAMs is published under a single part of the directory. There are
four mappings, which are represented by two subtrees located under
any part of the DIT. For the examples the location defined below is
used:
OU=MIXER MCGAMs, O=Zydeco Plc, C=GB
These subtree roots are of object class subtree, and use the
mechanism for representing subtrees defined in [1].
X.400 to RFC 822 This table gives the equivalence mapping from X.400
to RFC 822. There is an OR Address tree under this. An example
entry is:
PRMD=Isode, ADMD=Mailnet, C=FI, CN=X.400 to RFC 822,
OU=MIXER MCGAMs, O=Zydeco Plc, C=GB
RFC 822 to X.400 There is a domain tree under this. This table holds
the equivalence mapping from RFC 822 to X.400, and the gateway
mapping defined in RFC 1327. An example entry is:
DomainComponent=ISODE, DomainComponent=COM,
CN=RFC 822 to X.400,
OU=MIXER MCGAMs, O=Zydeco Plc, C=GB
The values of the table mapping are defined by use of two new object
classes, as specified in Figure 1. The objects give pointers to the
mapped components.
