directory schema에 정의되어 있는 attribute syntax의 값을 보세요...

님이 쓰시는 ldap server가 어떤 것인지는 모르겠지만, openldap의 경우 directory들 중에 schema란 이름을 가진 놈이 있을 것입니다. 거기에 있는 파일들에, 어떤 attribute는 어떤 syntax(type)을 가지는 가가 명시되어 있습니다.

예를 들어..

attributetype ( 2.5.4.41 NAME 'name'

EQUALITY caseIgnoreMatch

SUBSTR caseIgnoreSubstringsMatch

SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )

에서 보면 name의 syntax가 머라머라고 되어 있습니다.

여기서 1.3.6.1.4.1.1466.115.121.1.15는 type입니다.

아래 표에서 보면, H-R(human-readable)한 directory string이죠....

rfc2252에 정의된 syntax들은 다음과 같습니다.

A suggested minimum upper bound on the number of characters in value

with a string-based syntax, or the number of bytes in a value for all

other syntaxes, may be indicated by appending this bound count inside

of curly braces following the syntax name's OBJECT IDENTIFIER in an

Attribute Type Description. This bound is not part of the syntax

name itself. For instance, "1.3.6.4.1.1466.0" suggests that

server implementations should allow a string to be 64 characters

long, although they may allow longer strings. Note that a single

character of the Directory String syntax may be encoded in more than

one byte since UTF-8 is a variable-length encoding.
