Reading custom attributes/Object Classes from Ping Directory

To Whom It May Concern:

I am new to Sailpoint (coming over from NetIQ Identity Manager). Regardless, I am trying to setup/modify our current connection to our PingDirectory server. In short, I have created some custom attributes/objectclasses in PingDirectory and I am having trouble trying to figure out where to import the new schema so that I can add these custom attributes/objClasses to the application definition.

Part of the problem may be that the version of SailPoint my be too old (version 8.0). Can anyone give me some pointers on importing the schema so that I can populate these new custom attributes?

Thanks in advance,
