mount_smbfs no longer works

[Wojciech Puchar]

i upgraded samba to version 4.10 on server side.

Windows see it well. all works both shares, domain server, roaming 
profiles.

Mac OS mounts it

FreeBSD doesn't.
passwords are fine in .nsmbrc

i have

//wojtek at SERWER/wojtek /dgs-wojtek smbfs rw,noauto,-u=1003,-g=1003,-N,-I192.168.0.241,-T60,-WDGS,-Eutf8:utf8 0 0

in /etc/fstab

and

[192.168.0.241:WOJTEK]
password=xxxxx


worked before change. now i'm getting

mount_smbfs: unable to open connection: syserr = Authentication error


is something special needed to make it work?
