The GetIdentitiesOnObj
method returns Person, IdentityGroup, and Role objects that have permissions
defined on a specified resource. Flags can be set to return the identity's
DisplayName value and a value describing the origin of the permission.
When the specified resource
is an ACT object, the method lists the identities that are assigned
permissions to protect the ACT, unless the SECAD_ACT_CONTENTS flag
is set. When this flag is set, the method lists identities that have
permissions defined in the ACT.
