Change subject: sdk: Register only relevant auth schemes ...................................................................... sdk: Register only relevant auth schemes Currently the SDK uses the default set of authentication scheme factories, but some of them can't be used even if the server supports them because the SDK may not have the required credentials. For example, the caller may have initialized the SDK activating Kerberos but without providing a user name and password: Api api = new ApiBuilder() .url("https://...") .kerberos(true) .build(); This is completely normal. But the server may support both Kerberos and Basic authentication, responding with the following headers: WWW-Authenticate: Negotiate WWW-Authenticate: Basic realm="My realm" In this case the underying HTTP library will first try to use the Negotiate authentication scheme, and if it fails (there is no TGT in the Kerberos credentials cache, for example) it will try Basic. But basic will not work because the SDK doesn't have any valid credentials, and will actually generate a NPE. To avoid this issue this patch changes the SDK so that it only registers the authentication schemes it has credentials for.
