Changing an openLDAP schema programatically

[akpan Zouk <akpan101@yahoo.com>]

Hello all,

I just joined the group. I searched the archives but
didn't find a 
solution to my problem. Apologies if it has been
discussed. Here is the 
problem:

I have an objectclass thus defined in local.schema
thus:
 
objectclass ( 1.1.1.1.1.1.1.1.1 
    NAME 'newObjectClass' SUP top STRUCTURAL
	MUST ( cn )	
	)

I would like to add attributes to this objectclass,
but the names of the 
attributes are known at run-time; i.e. I don't know
the names of the 
attributes when I am creating the above objectclass. I
would there like to 
change this definition at run time. Does openLDAP
support this 
capability?

I tried the following using Novell's Java Library
connecting to an 
openLDAP server:

//  add attribute 'userPassword'. Note that 'cn' and 
// 'userPassword' are already defined in core.schema

String[] requiredAttr = new 
String[]{"cn","userPassword"};   

LDAPObjectClassSchema newObjclass = new 
	LDAPObjectClassSchema(
                 new String[] {"newObjectClass"},
                 "1.1.1.1.1.1.1.1.1",
                 new String[]{"top"},
                 "",
                 requiredAttr ,
                 optionalAttr ,
                 LDAPObjectClassSchema.STRUCTURAL,
                 false);
                 
                 
try{
    LDAPSchema schema = new LDAPSchema();
    schema.modify(newObjclass);
    schema.saveSchema(ldapConnection);
 } catch (LDAPException e){
    e.printStackTrace();
 }


I got an "unwillingToPerform exception"!!. Any ideas
why this 
happens?

Thanks
Akpan
