[pve-devel] [PATCH access-control] api: domains: fix setting only the realm authentication password

[Christoph Heiss]

Previously, if one tried to only update e.g. the bind password for an
LDAP realm, it would fail with an rather unhelpful error message:

  # pveum realm modify ldap -password foo
  update auth server failed: no options specified

The root cause was that the `password` parameter was removed early from
the parameter object, which than would fail the check whether it is
empty or not.

Thus, additionally check if only `password` was specified and if so,
allow it.
