Deployed NEO4j on a hardened RHEL7 using ansible. No constraint can be created even though the DB is empty. Any idea on how to debug this or what could be the cause? Other objects can be created. It seems to be a problem with some core library... We have the same install on another instance which works fine, so I suppose it must be something related to the deployment...even though there were not install errors
Thanks.
