Problem: When using "anyauth" authentication type for a proxy server that has been configured to use Negotiate&NTLM&Digest&Basic the adcdiag utility will produce an CLDINST error stating that it failed to connect to Centrify Identity Platform.
Cause: The issue is due to a bug in the stock curl library and how it handles the above configuration (in the problem section). This issue does not affect the operation of the actual adclient process.
Workaround: Use anyauth with the proxy server configured to use Negotiate only, Basic only, NTLM only or Digest only.
Resolution: This issue has been fixed in release 18.11 where we changed the code to detect the authorization type supported by the proxy server and simply use that supported authtype instead of "anyauth".
