NDES_Admin account deletion after implementation of SCEP for iOS enrollment

Hello,

I'm hoping somone might have an answer for this.  Is the NDES_Admin account (per Microsofts SCEP configuration guide) needed after NDES has been fully deployed and Mobile Manager functionality has been proven?  We are fully live with Mobile Manager and are able to enroll iOS devices without any issues.  However, the NDES_Admin account which was used during the setup of the NDES service, recently came up due to an audit.  So now the question is, do we really need this account?  Does it need to be an Enterprise Admin account at this point?  Any advice would be helpful.

Thanks.
