Hi, all:
I have two questions on schema
definition:
1. In order to obtain the schema information from
cn=subschema, I modify the following
three attrbiute definitions in
core.schema:
attributetype (
2.5.21.4 NAME 'matchingRules'
EQUALITY objectIdentifierFirstComponentMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.30 ) attributetype (
2.5.21.5 NAME 'attributeTypes'
EQUALITY objectIdentifierFirstComponentMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.3 ) attributetype (
2.5.21.6 NAME 'objectClasses'
EQUALITY objectIdentifierFirstComponentMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.37 ) the words "USAGE directoryOperation" for
the above attributes are removed. By doing this,
I can use Netscape Java SDK to obtain
schema information, and everything works well.
This approach is the result under many
try-and-error testing. What is the risk to modify
the above definition?
2. In order to store non-UTF8 code in some standard
attributes, I modify the the definition of Attribute name as
follows:
attributetype (
2.5.4.41 NAME 'name'
EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.5{32768} ) The original syntax
"1.3.6.1.4.1.1466.115.121.1.15" is modified as
"1.3.6.1.4.1.1466.115.121.1.5"
to store non-UTF8 code. Also,
everything seems well on any operation(add, modify,delete,search).
What's the risk to such
modification?
Could someone give me some idea?
Thank you very much!
SCW
