User Accounts Created by Microsoft Provisioning
Microsoft Provisioning Framework (MPF) creates two user
accounts: the MPF service account (MPFServiceAcct) and the MPF
client account (MPFClientAcct). For domain deployments, these
accounts are installed in the Active Directory directory service.
For local installations, these accounts are installed in the
Microsoft Windows operating system as workgroup accounts.
MPFServiceAcct is the default account for provisioning servers.
It has permissions to run provisioning engines, queue managers, and
auditing and recovery managers.
When you are setting the password for MPFServiceAcct during
setup, the following important conditions apply:
If you ever change the password for the MPFServiceAcct, you
will also be required to change the password for the provisioning
engine COM+ application, Provisioning Queue Manager service, and
Provisioning Auditing and Recovery service. If you do not do this,
MPF will not function properly. Multiple forests with different
provisioning engines should not use the same MPFServiceAcct
password. If they do, MPF replicates objects across the forests.
This is appropriate only if all domains use the same provisioning
MPFServiceAcct is a member of the MPFServiceAccts and
When a request uses basic authentication, Kerberos delegation,
or has a procedure with an "execute as" credential, these
credentials take precedence over MPFServiceAcct. In MPF deployments
that perform security checking outside of MPF, you might find it
useful to grant permissions to MPFServiceAcct so it can perform
actions on external services.
MPFClientAcct is only used to submit Simple Object Access
Protocol (SOAP) requests to MPF through SOAP Internet Server
Application Programming Interface (ISAPI). MPFClientAcct is a
member of the MPFClientAccts group.
When you are setting the password for MPFClientAcct during
setup, if you change the password for the MPFClientAcct, you will
also be required to change the password for SOAP ISAPI.
Accounts are created during MPF setup. If you have a setup
failure, you must delete these accounts manually before you attempt
