Allow using empty password in smb/smb2 protocol

Use case:

I am a user who used anonymous access to samba shares in CloverDX 6.1 or older. I've been using URL like this in FlatFileReader: smb2://virt-pink/some/path/data.txt

On some servers this kind of access stopped working in 6.2. I would need to configure my samba server to stop requiring message signing to make it work.

I don't want to re-configure my server in that way. Instead I want to access my server using a user with no password, with urls like this:

• smb2://someUser:@virt-pink/some/path/data.txt

• smb2://someUser@virt-pink/some/path/data.txt

This will mean that I might have to create that user on the server side, but it is easier or more acceptable than disabling message signing setting of the server.
