Click the namespace that has the procedure for which you want
to view or modify the credentials.
In the details pane, right-click the procedure, and then click
On the General tab, select the Execute as check
box, in the corresponding text box, click the credentials to be
used, and then click OK.
The Execute as option is not available until you have
set up at least one credential under Credentials in the
Provisioning Manager console tree. The Execute as option is
not available for procedures of read-only namespaces.
To open Provisioning Manager, click Start, point to
Programs, point to Microsoft Provisioning Server, and
then click Provisioning Manager.
The red highlighting for a namespace in the console tree
indicates a read-only namespace. You can make only limited
modifications to the procedures of a read-only namespace. The
modifications that can be made are not the same for all read-only
namespaces and their procedures.
