You’ll also need to run “service centrifydc stop” on all those VM’s (at DCC). Otherwise it will still attempt to authenticate with AD and won’t use the local account.
Thanks-

Subject: Re: Akamai config for put/post
Thanks for the help Ruchika and Don! Just to close the loop on this. The issue turned out to be sending a payload with a DELETE request. Here are the final notes from a meeting with Akamai.

Thank you for your time over the phone. Recap of discussion over the phone :
- This issue is observed in the cases if the first request method is Delete , and contains a payload and the next requests uses the same persistent connection
- The latest HTTP RFC states that there are no defined semantics for payloads in DELETE requests (https://tools.ietf.org/html/rfc7231#page-29).
- It doesn’t specifically say they should be allowed or denied but mentions that a server may reject the request
- We don’t deny this requests. However the payload is added to the subsequent request causing the request to fail
- The fix will be to either remove delete payload, or deactivate persistent connection between Akamai and client for Delete method
- As discussed we can remove the payload from Delete , and will re run the tests to confirm if the issue is fixed.
