create new object in Active Directory

Hi,

Sorry for the novice question, but I'm trying to create a new class object so that any other system admin can create a new instance of it in Active Directory (as when adding a new user or group).

I created 2 attributes and 1 class with ADExplorer:

cn: myAttribute1

objectClass: attributeSchema
attributeID: 1.3.6.1.4.1.38971.1.1.2
attributeSyntax: 2.5.5.12
isSingleValued: FALSE
adminDisplayName: myAttribute1
adminDescription: myAttribute1
oMSyntax: 64
searchFlags: 1
lDAPDisplayName: myAttribute1
systemOnly: FALSE

cn: myAttribute2
objectClass: attributeSchema
attributeID: 1.3.6.1.4.1.38971.1.1.1
attributeSyntax: 2.5.5.12
isSingleValued: FALSE
adminDisplayName: myAttribute2
adminDescription: myAttribute2
oMSyntax: 64
searchFlags: 1
lDAPDisplayName: myAttribute2
systemOnly: FALSE

cn: myClassObject
objectClass: classSchema
governsID: 1.3.6.1.4.1.38971.1.2.1
rDNAttID: cn
adminDisplayName: myClassObject
adminDescription: myClassObject
objectClassCategory: 1
lDAPDisplayName: myClassObject
name: myClassObject
systemOnly: FALSE
subClassOf: groupOfNames
mayContain: myAttribute1
mustContain: myAttribute2

I rebooted the AD server.

I registered the schema management DLL and loaded it in MMC.

I confirmed that the object and attributes were there.

However, I have two issues:

1) I'd like to be able to add new myClassObject instances from the serverr's control panel instead of using AdExplorer or an ldif file. The object myClassObject  does not appear in the "create new" drop-down menu.

2) If I create a myClassObject instance with AdExplorer, and then assign a user as member all seems to work as expected except when I browse to the properties of the AD user, open the "membership" tab, scroll down the different groups, but as soon as I hover over and click myClassObject  with the mouse, the AD console crashes with an unknown error (nothing useful in the log).

Any ideas?

Anything wrong in my object/attribute definitions above?

Thanks
