[midPoint] Circular dependency error

[Rodrigo Yanis]

Hello everyone,

We're currently experiencing an issue with an LDAP driver throwing a
Circular Dependency error when attempting to delete a provisioned user.
We've configured the driver to be dependant on an Scripted SQL driver.

The error stacktrace (on debug) is the following:

Please note that *00000000-0000-1de4-0002-000000000004* stands for the
resource's OID to which our Active Directory resource is dependant.

We're not sure why this is happening - it seems like the
dependencyProcessor is reevaluating provisioning for the Active Directory
projection and failing as the dependency was already deprovisioned.

Do you have any insights on this?

Thanks,

*Rodrigo Yanis.*
