To create the new app in the NS, I use
oc new-app -e MONGODB_USER=test,MONGODB_PASSWORD=test,MONGODB_DATABASE=testdb,MONGODB_ADMIN_PASSWORD=testadm,MONGODB_NOPREALLOC=true,MONGODB_SMALLFILES=true    --name='mongo324' mongo:3.2.4
Then in the origin console, I see :
error: failed switching to "mongodb": operation not permitted
In my local space policy I have
-bash-4.2$  oc describe policyBindings :default
Name:                                   :default
