Description

https://github.com/apache/mesos/blob/1.4.0/src/uri/fetchers/docker.cpp#L843

This failure message is not accurate. For such a case, if the user/operator give a wrong credential to communicate to a BASIC auth based docker private registry. The authentication failed but the log is still saying: "Unsupported auth-scheme: BASIC"
