Explanation: From Microsoft Pre-sale Technical Support Engineers, how to expand Ad Schema
1. Use Oidgen.exe in Windows2000 Resource Kit Tools to generate Attribute's OID 2, open the Active Directory Schema MMC console, right-click Attribute, select New-Attribute. 3. In the pop-up CREATE New Attribute window, fill in the description of the property, and the OID generated in step 1. 4. Continue to specify the type of attribute (character / integer ... ..), maximum and minimum 5, if you want to define this property into an "array", you can check "multi-value". 6, determine, save 7, right-click User object on the Active Directory Schema MMC console, select Properties 8, click "Add" on the "Attributes" tab, connect the properties you just created to the User object Note: Because the OID is An X.500 standard resource is to apply to the management agency of X.500, so Oidgen.exe can only generate two OIDs to the user under the OID space belonging to Microsoft, one OID is used from definition "classes" One OID is used from definition "properties". In addition, Oidgen.exe is not a free software, which belongs to part of Windows2000 Resource Tools Kit (this tool is not included in the free download section of Win2000 Resource Tools Kit). If you need this tool, you need to purchase Windows2000 Resource Tools Kit. After completing the extension of Ad Schema, your application can read and write these custom user properties through LDAP or ADO.
