Healthcheck always unhealthy if no anonymous access allowed.

Description

The healthcheck fails for me because smbclient also exists with a non zero error when "NT_STATUS_ACCESS_DENIED" is returned (e.g. no anonymous access).

I'm using smbclient -L \\localhost -U % -m SMB3 | grep -q 'NT_STATUS_ACCESS_DENIED' || { [ $? -ne 0 ] && exit 1; } as an override wich does no longer report as unhealthy when anonymous is not allowed but still triggers unhealthy on timeout (e.g. NT_STATUS_IO_TIMEOUT) for example.

Expected behaviour

Don't fail healthcheck if everythings working

Actual behaviour

Fails when it should be healthy

Steps to reproduce

docker-compose up -d

Wait

docker inspect --format "{{json .State.Health }}" samba | jq reports unhealthy

Here's a new version, the above one failed if anonymous/guest was allowed. The following seems to work for both cases so far:

healthcheck:
    test: ["CMD-SHELL", "out=$(smbclient -L \\\\localhost -U % -m SMB3 2>&1); rc=$$?; printf '%s\n' \"$$out\" | grep -q 'NT_STATUS_ACCESS_DENIED' && exit 0; [ \"$$rc\" -ne 0 ] && exit \"$$rc\" || exit 0"]
    interval: 30s
    timeout: 10s
    retries: 1

Nice! That works for me...
