[Samba] smbd starts but terminates with - failed to receive smb request

[Scott Classen]

Hello,

I start smbd interactively from the command line and then attempt to issue an smbtree command from another terminal and smbd immediately terminates.

Here is the output. It looks like the initial authentication is working, but the termination happens after "string_to_sid: SID root is not in a valid format"

Any idea what might be going on here?

Thanks
