[ovirt-users] User with SuperAdmin Role has not MANIPULATE_STORAGE_DOMAIN

Hi list, I set the SuperAdmin Role on a AD group. I use my account in this group to use oVirt. I try today to add an Export Domain but I failed with this error in log : 2016-01-07 16:46:28,883 INFO [org.ovirt.engine.core.bll.storage.AttachStorageDomainToPoolCommand] (default task-1) [68d5410a] No permission found for user '8ac67747-110c-4125-86f1-1f52ca0e7705' or one of the groups he is member of, when running action 'AttachStorageDomainToPool', Required permissions are: Action type: 'ADMIN' Action group: 'MANIPULATE_STORAGE_DOMAIN' Object type: 'Storage' Object ID: 'c7dee64d-a27e-446e-8656-cef2d8ea42a6'. Where can I set the good permission ? Thanks a lot --- Kevin C
