- If MinIO is configured with LDAP then users and groups are external, and
the credentials provided in the CONSOLE_ACCESS_KEY and
CONSOLE_SECRET_KEY env vars will belong to an existing user in the active
directory, therefore we need to authenticate first with
`credentials.NewLDAPIdentity`
- Fixed race condition bug in which TLS RootCAs certs were not loading
correctly (certPool was always null)
- Fixed TLS bug in which if Console was deployed without TLS enabled
RootCAs certs were not loading
- Initialize LDAP Admin credentials once
- Initialize stsClient once
