Trying to reproduce #14934, I got:

In curl:

{"action":"createDirective","id":"","result":"error","errorDetails":"Could not create Directive <- Could not save Directive  <- Can't execute LDAP request"}

In webapp console:

WORKAROUND: provide an uuid in JSNO:

{
  "displayName": "My Directive",
    "enabled": true,
    "id": "66b962cb-a039-4bf9-8e52-4ff10aeb6542",
    "longDescription": "",
    "parameters": {
....
