LDAP API Calls from Operator failing in 7.0.0

Hi,

We've started running tests against 7.0.0 (this was the first run on 7.0.0-4390) with the Autonomous Operator and have found issues with LDAP; we're using the API endpoint /settings/ldap/validate/connectivity and are receiving the response;

timeout: unexpected status code: request failed POST http://127.0.0.1:57096/settings/ldap/validate/connectivity 400 Bad Request: Invalid JSON

These tests have not been changed on our end, and are functioning and passing fine against other couchbase versions (6.6.0 (release), 6.5.2-6625). This is very hard for us to troubleshoot, as I cannot find any documentation for this API endpoint, nor any release notes detailing any LDAP-related changes.

As this is a regression against 6.6, it makes testing & certifying against multiple versions next to impossible.

There are some more details available in K8S-2001.
