Nomad v1.1.0 introduced consul namespaces support when using Nomad Enterprise + Consul Enterprise, however we broke functionality around ACL validation in the OSS use case.

Jobs are incorrectly being blocked when following conditions are true

  • Submitting a Consul Connect job
  • Consul is OSS
  • Consul ACLs are enabled
  • Nomad's allow_unauthenticated is set to false

The error looks like,

$ nomad job run -consul-token 76221243-1631-e241-9b34-ffbcb6c36025 api.nomad 
Error submitting job: Unexpected response code: 500 (job-submitter consul token denied: consul ACL token cannot use namespace "default")

Which is nonsensical, since Namespaces do not exist in Consul OSS.

consul: correctly check consul acl token namespace when using consul oss
09c9a17 
This PR fixes the Nomad Object Namespace <-> Consul ACL Token relationship
check when using Consul OSS (or Consul ENT without namespace support).

Nomad v1.1.0 introduced a regression where Nomad would fail the validation
when submitting Connect jobs and allow_unauthenticated set to true, with
Consul OSS - because it would do the namespace check against the Consul ACL
token assuming the "default" namespace, which does not work because Consul OSS
does not have namespaces.

Instead of making the bad assumption, expand the namespace check to handle
each special case explicitly.

Fixes #10718
