ADSI Adjust classes in Active Directory Schema

Hey,

I have a problem with my script. I have to make a few attributes and classes in Active Directory. This works but now I have to add the newly created attributes as optional attributes for the object “user”.

Normally this should do the trick.

objClass = GetObject("LDAP://cn=user," & objRootDSE.Get("schemaNamingContext"))
objClass.GetInfo
objClass.Put "mayContain", Array("1.3.6.1.4.1.11256.0.0.2.0.1","1.3.6.1.4.1.11256.0.0.2.0.2","1.3.6.1.4.1.11256.0.0.2.0.0","1.3.6.1.4.1.11256.0.0.1.0.0","1.3.6.1.4.1.11256.0.0.1.2.0","1.3.6.1.4.1.11256.0.0.1.1.0","1.3.6.1.4.1.11256.0.0.1.1.1","1.3.6.1.4.1.11256.0.0.3.0.0")
objClass.SetInfo

I get an error on the first line saying:

Text: "Wrong number of arguments or invalid property assignment"
Code: 800A01C2

Can anyone help me?

Greetzz and tnx
