When running the following test
"[sig-storage] In-tree Volumes [Driver: cinder] [Testpattern: Dynamic PV (block volmode)] volumeMode should not mount / map unused volumes in a pod [LinuxOnly] [Skipped:NoOptionalCapabilities] [Suite:openshift/conformance/parallel] [Suite:k8s]"

It fails because the volume fails to create. That happens when using a storage class with provisioner: kubernetes.io/cinder. When creating a volume where the 
provisioner is  cinder.csi.openstack.org the volume is created.

This behavior doesn't happen when not using app credentials.

From CSI provisioner logs:
