Also, RFC 2256, Section 5.42 says:
"... LDAP server implementations which do not support
attribute subtyping ... Client Implementations MUST NOT assume that LDAP servers
are capable of performing attribute subtyping."

I just want to confirm. I believe it's implicit in the following statements: 3.2.2: Servers which follow X.500(93) models SHOULD implement subschema using the X.500 subschema mechanisms, and so these subschemas are not ordinary entries. LDAP clients SHOULD NOT assume that servers implement any of the other aspects of X.500 subschema. The first sentence implies that servers may not follow X.500(93). 3.3: LDAP can be mapped onto any other directory system so long as the X.500 data and service model as used in LDAP is not violated in the LDAP interface. The interface is not violated if subtyping is not supported. |
