mounting CIFS share (tcp/445) with FreeBSD and mount_smbfs(8)

I need to mount a CIFS share from windows server 2012 r2 via CIFS, tcp/445 as NetBIOS
service (tcp/139) has been deprecated due to serious vulnerability issues.
Until the disabling of NetBIOS and tcp/139 we used successfully autofs and mount_smbfs.
this is no longer working. I tried to force autofs/mount_smbfs to bind to port 445 on the
server via ://@xxx.xxx.xxx.xxx:445/sharename, but this doesn't work.
Trying to mount a share from a samba 4.3 server (FreeBSD CURRENT, net/samba43, both most
recent sources), where I configured samba_server via smb ports = 445 to use port tcp 445
only and only SMB2 and SMB3 (server min protocol = SMB2) protocols via the following
mount_smbfs -I xxx.xxx.xxx.xxx -U a_user -W \
WORKGROUP //a_user at xxx.xxx.xxx.xxx:445/sharename /mnt
results in the error
mount_smbfs: unable to open connection: syserr = RPC struct is bad
Setting "smb ports = 139,445" and "server min protocol = NT1" seems to work, the share
can be bound, but this is SMB over tcp/139 and not CIFS.
I desperately need CIFS and I need tcp/445 since tcp/139 is from now on firewalled.
So: what do I miss here?
Kind regards and thank you in advance,
P.S. Please CC me
