Minio: Handle wrong formatted MINIO_ACCESS_KEY

Created on 16 Mar 2019 · 3Comments · Source: minio/minio

minio does not complain about an access key like "bWluaW8=". Instead, it returns 400 on any request.

Expected Behavior

If an access key like "bWluaW8=" is not allowed, minio should complain during startup phase. Additionally, the returned error should be self-explanatory, e.g. "The access key provided contains bad characters".

Current Behavior

minio does not complain about an access key like "bWluaW8=". Instead, it returns 400 on any request.

mc: <ERROR> Unable to initialize new config from the provided credentials. Missing fields in request.

Currently, a non well formatted access key leads to non-concluding errrors.
