Need a Reply - Identity Management and Exadata

Experts and Colleagues,

My customer is challenged implementing identity management on Exadata. My customer has an internal auditing requirement to manage linux user ids via AD, LDAP, OUD, other centralized repository, etc.

In these instances, additional packages need to be uninstalled/reinstalled/reconfigured when applying a QFSBP. Given that we are talking about an engineered system, my customer would like to avoid making

any changes or installing software that might break BP install scripts or cause other unforseen issues in the future.

Identity/account management is typically something included in enterprise software. Are there knowledge docs, etc. that address this? Can anyone advise on best approach?
