Hello gurus, When I have this piece of schema included in my slapd.conf file... attributetype ( 1.3.6.1.4.1.11.11.1.1.1.1.402 NAME ( 'TestCountryString' 'TestCountryStringSyn' ) DESC 'Test Country String' EQUALITY caseIgnoreMatch ORDERING caseIgnoreOrderingMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.11 SINGLE-VALUE ) ... my 2.4.32 slapd -Tt complains with this error: line 8 attributetype: AttributeType inappropriate matching rule: "caseIgnoreMatch". My understanding of http://tools.ietf.org/html/rfc4517 is that caseIgnoreMatch is valid for country string: "The caseIgnoreMatch rule compares an assertion value of the Directory String syntax to an attribute value of a syntax (e.g., the Directory String, Printable String, Country String, or Telephone Number syntax) whose corresponding ASN.1 type is DirectoryString or one of its alternative string types. " Could you confirm whether this is a bug in openldap or simply a misunderstanding from me ? Thanks in advance ++Cyrille
