Provisioning Active Directory Groups and Audit Logging (HSP_AUDIT_RECORDS, *.ATX, etc)

We are switching from having individual users from Active Directory provisioned in Shared Services to provisioning Active Directory groups in Shared Services.  If we use this provisioning method will we:

1. Lose the ability to identify the individual who make data entry submissions.  That is, will it be the AD group names appear in the audit logs instead of the individual who is a member of the group?
2. Will the calc execution logs show the group name or the individual name.

Thank you,
