Inappropriate matching (18): additional info: modify/delete: postalAddress: no equality

[Michael Ströder <michael@stroeder.com>]

HI!

using OpenLDAP 2.4.10 (RE24) I'm trying to explicitly delete a value of 
attribute postalAddress:

---------------------------------------------------------------
dn: cn=Fred Feuerstein,ou=Testing,dc=stroeder,dc=de
changetype: modify
delete: postalAddress
postalAddress: zeile 1$zeile 2$zeile 3
-

---------------------------------------------------------------

But this results in an error:

modifying entry "cn=Fred Feuerstein,ou=Testing,dc=stroeder,dc=de"
ldapmodify: Inappropriate matching (18)
        additional info: modify/delete: postalAddress: no equality 
matching rule

But postalAddress is declared in the schema like this:

( 2.5.4.16 NAME 'postalAddress' DESC 'RFC2256: postal address' EQUALITY 
caseIgnoreListMatch SUBSTR caseIgnoreListSubstringsMatch SYNTAX 
1.3.6.1.4.1.1466.115.121.1.41 )

Aarrgh! What's up with that? If the equality matching rule is not 
implemented it should not be announced in the subschema. The server 
should not simply report what might have been defined in some RFC.

Background: When generating deltas in web2ldap attribute values are now 
explicitly deleted if there's an EQUALITY matching rule defined for an 
attribute type. This is done to prevent applying changes in case an 
entry and its attributes was changed during the user editing the entry.

Ciao, Michael.
