hi,

I create the ldif to modify the schema ( ADD, modify, etc).

1. Is it possible to add some logic in the ldif ?
Something liks If the objectclass doesn't exist, then create the add
objectclass. If the attribute doesn't exist, then create else not create.

2. I created the attribute "Attrib1" , When I add this attribute to the
exist objectclass, Why I have to use the OID. When I use "Attrib1", Error
return "No such attribute". What problem when I create the attribute, Is it
some parameter is missing.

dn: CN=attrib1,CN=Schema,CN=Configuration,DC=X
changetype: add
adminDisplayName: attrib1
adminDescription: attrib1
attributeId: 1.2.840.113556.1.4.997
attributeSyntax: 2.5.5.8
cn: attrib1
description: Attribute testing2
isMemberOfPartialAttributeSet: FALSE
isSingleValued: TRUE
lDAPDisplayName: attrib1
distinguishedName: CN=attrib1,CN=Schema,CN=Configuration,DC=X
objectCategory: CN=Attribute-Schema,CN=Schema,CN=Configuration,DC=X
objectClass: attributeSchema
oMSyntax: 1
name: attrib1

dn: CN=StructObjClass1,CN=Schema,CN=Configuration,DC=X
changetype: modify
add: maycontain
mayContain : 1.2.840.113556.1.4.997 ( Why doesn't work on "mayContain :
Attrib1")

Thx for help
