Section 8 of the SAP UM Fanout driver docs (IDM 4) talks about the three
entitlement granting agents (Entitlements Service driver, Workflow, and
Roles and Resources driver via RBPM).

Then it says:

"The RBPM is the only supported entitlement agent for the fan-out
configuration of the driver."

Why? What is unique about the RBPM grants that are different than the
other two?

I am exploring how entitlements work, and I cannot see a reason for
this... The only thing that comes to mind, might be a requirement for
some value in the entitlement that cannot be generated for the others.
(Aka In the XML payload in the path.xml component of the
DirXMl-EntitlementRef).

On that note, does anyone have handy the path.xml from a sample user
with an entitlement?

I am collecting what they look like from the various sources. I have
one from RBE already: (Valued entitlement example).

<ref>
<src>RBE</src>
<id>services\IDM\DriverSet\Entitlement Policies\UserAccount</id>
<param>Student</param>
</ref>

I am trying to find a sample from RBPM via Roles and Resources drivers,
and one from a Workflow granted entitlement. Any one have one handy?
