Okay the '%' were due to bad coy paste between the source code and a
local smb.conf.
The samba is running on a minimal and embedded environment, which is why it must
be built using buildroot.
It turns out that we might have been too restrictive with the samba libraries
embedded in our environment.
I've solved this issue using latest version available in buildroot (4.19.3)
and making sure all samba libraries are there.
The command "net ads join" now works well and I can connect to a share
using AD authentication without netbios.
One last thing though : I've to do a new join after each reboot because a
large part of the system is not persistent at reboot (like the whole /var
directory that's flushed).
The only thing for which I do backup is the passdb.tdb and the secrets.tdb
(historically for local users authentication).
Are there other things to backup to avoid the Kerberos pre-authentication issue
after reboot?
Thanks for your help
Vincent

It sounds like you built Samba yourself, if so, why ? Also why use an old
version ?

Why the double '%' ?
It should be just one e.g. 'valid users = %U'
You do not actually need the 'path' parameter in '[homes]', it
is set in '[global]'
Having said that, it has nothing to do with your problem, which is that you do
not want to use netbios.
I said in my last post:
If 'disable netbios = yes' is set in smb.conf, then netbios
shouldn't be used by Samba and you shouldn't be having problems with it.
Try adding 'disable netbios = yes' to your smb.conf , stop nmbd and stop
it from starting again. Restart Samba and see if your problem has gone away, it
should have.
