If ksmbd.mountd is configured to assign unknown users to the guest account ("map to guest = bad user" in the config), ksmbd signs the response. This is wrong according to MS-SMB2 3.3.5.5.3: 12. If the SMB2_SESSION_FLAG_IS_GUEST bit is not set in the SessionFlags field, and Session.IsAnonymous is FALSE, the server MUST sign the final session setup response before sending it to the client, as follows: [...] This fixes libsmb2 based applications failing to establish a session ("Wrong signature in received").
