Matching Rules and RFC questions

[Richard F. <fer...@sp...>]

Hello there,

I have the following RFC questions regarding LDAP. Is there someone 
there who can answer these questions?

1) RFC 2252 section 6 states "Server SHOULD recognize all the syntaxes 
described in this section.
Then on RFC 2256 section 6 states the same thing as above. However, 
the syntax list between both RFCs are not the same. So does RFC 2256 
supercede 2252? If not why is there a conflict on the recommended 
syntaxes. 


2) RFC 2252 lists 21 matching attribute but I have discovered three 
more: 
octetStringMatch
authPasswordExactMatch
authPasswordMatch

Are the above new matching rules part of a new LDAP RFC release or just 
proprietary to certain directory servers.


3) I work with Active Directory and eTrust (X.500) directory and when I 
look at their schema objects (attribute, class and syntax definitions) 
I do not see any schema objects for matching rules. Well if the 
matching rules are not in the schema how can you use them?

4) Can you reference me to a good LDAP web site that has up to date RFC 
resources?

Thank you ,
Richard
