For a disconnected system, during certification the access has been revoked and manually delete the access from the source after being revoked. However, when I tried to do certification again for the same user. The access profile is still showing in certification. What could be the issue?
Did you aggregate the source after the access was removed?
In order for IdN to know about the change in access for a disconnected source a new file would need to be created and loaded in IdN. This will cause the access to fall of the users cube and remove them from the certification.
Is there an SDIM for the source or was the revocation a task in SailPoint?
