samba error: “session setup failed: NT_STATUS_LOGON_FAILURE” when adding new user

but when i add new user to share samba it didn’t work, it continue to produce “session setup failed: NT_STATUS_LOGON_FAILURE”

i tried both using straight connection smb://server/sharename or by smbclient connection.

It’s been an awkward condition in the host I’ve been setting. It is that the application windows live mail unable to run properly in non administrative user. for example, I can’t delete or add contact in user level, but I can do it in administrator level.
