[VU+ Duo2] samba crashes when configured to user security

[skortela]

Vu+ Duo2
OpenVix-HD Apollo 077

Samba crashes when configured to be used as non-root (user security with multiple users, see smb.conf below).

I wan't samba to be configured to be used with multiple users and each user own homefolder. Password secured.

Error log attached.
According to some web post, this happends when samba is wrongly builded:
