Hi Tom,

as for the not-deleted-projection i believe you need to configure your
projection policy and also check your schemaHandling/existence if changed.

see https://wiki.evolveum.com/display/midPoint/Projection+Policy

>    - The user 'Testuser' has an assignment to the empty 'Root-Role'.
>
> 2) In the second step, I edit the role 'Root-Role':
>
>    - The 'Resource-Role' has an account construction inducement for a
>    resource (e.g. dummy CSV).
>    - The 'Root-Role' has an inducement to the 'Resource-Role'.
>
> Because of MidPoint's eventual consistency, I start a Recomputation of all
> 'Root-Role' members.
>
> A projection for the resource is created for the 'Testuser'. So far so
> good.
>
> 3) In the third step, I edit the role 'Root-Role' again:
>
>    - The inducement to 'Resource-Role' is removed from the 'Root-Role'.
>
> To regain consistency, I start a Recomputation of all 'Root-Role' members
> again.
>
> Nothing happens.
> The user 'Testuser' still has his projection for the resource (which
> should be deleted).
> Only one thing happened: The <roleMembershipRef> to 'Resource-Role' was
> removed during Recomputation.

>
> The same bahaviour happened as I tried these variations:
>
>    - Deactivating the inducement ('Root-Role' -> 'Resource-Role') instead
>    of deleting it
>    - Reconciling the user 'Testuser' instead of starting the
>    Recomputation of all members of role 'Root-Role'
>    - Use different <strength> values for the construction inducement in
>    the 'Resource-Role'
>
>
> Sidenote: The system behaves in the same (wrong?) way, when I replace the
> construction inducement with a group projection.
> In this case, the user should already have an account in the resource.
>
> Interestingly, this operation still work:
>
>    - If I directly assign the 'Resource-Role' to the 'Testuser', the
>    projection is created correctly.
>    - If I remove the direct assignment of 'Resource-Role' from the
>    'Testuser', the projection is deleted correctly.
>
>
> Sidenote: The Enforcement Options of the resources are set to the default
> value ('relative' with no legalization).
> This should create accounts after assignment and delete accounts after
> unassignment.
> Other accounts in the resource should not be touched.
> The other Enforcement Options and the Legalization are not useful in my
> scenario (I don't want all unassigned accounts to be whiped from the
> resource).
>
>
> The problem seems to be, that the Reconcile/Recompute job doesn't know,
> that there had ever been an indirect assignment to the 'Resource-Role'.
> Instead, the job behaves like the projetion was created manually for the
> user.
> Because of this, there seems to be nothing to recompute for MidPoint.

> I assume, this causes the different treatment of direct and indirect

> Changes made to the role hierarchy would cause an effect during

> removed correctly right now.
