Host signing returns 403 even though login succeeds: the policy grants the literal path sshca/sign/host, but the only role on the sshca mount is signhost, so the grant matches nothing. Hosts named directly under unkin.net also fall outside the role's allowed domains.

  • Rename the policy to sshca/sign/signhost and grant that path
  • Allow unkin.net alongside main.unkin.net and consul on the signhost role

The sshca mount only defines the signhost role, so the policy grant for
sshca/sign/host never matched a real path and every host-key signing
request from the Puppet compilers was denied. The role also excluded
unkin.net, rejecting the git.unkin.net and grafana.unkin.net principals
the manifest sends.

- Grant sshca/sign/signhost instead of sshca/sign/host
- Add unkin.net to the signhost role's allowed_domains

Change this to be just the domain change, don’t rename the role.

The only role on the sshca mount is signhost, so a policy granting the
literal path sshca/sign/host matches no role and every host signing
request is denied after a successful login.

- Rename the policy to sshca/sign/signhost and grant that path
- Move the policy's state to the new name so the rename is tracked
