Problems with multiple names per OID
I guess this is kind of an FAQ, but I could not find an explanation so
far. If it is an FAQ, maybe someone give me just a pointer to the right
There are several cases where multiple names are defined for a single
OID, e.g. core.schema defines the names "street" and "streetAddress"
both for 188.8.131.52. The Administration Guide says that when attributes
are sent they are labeled with the first name. However, the other names
are also valid in requests. Now the problem is that some LDAP clients
send names in their requests that are known to the LDAP server as
"secondary" names, resulting in responses with other names than the
ones in the request. This results in clients not being able to process
the response correctly, although the requested data is available and
even sent back to the client.
Examples are Mozilla Thunderbird and Apple Addressbook which use
different (but only one) names for OID 184.108.40.206 and others.
My personal impression (though I'm new to LDAP, but have quite some
experience with SNMP/SMI, which is also heavily based on ASN.1) is that
LDAP's design is broken in that it does send non-unique labels instead
of unique (and more compact) OIDs in the protocol. But maybe, I'm just
missing a way how to handle the problem correctly.
