Celso, I've directed this to the samba technical team because I suspect 
that there is a problem using smbclient to connect to [homes] on FreeBSD.  
The only anomolies that I can see, is from the logs is 
"lp_servicenumber: couldn't find homes" or "tree connect failed: NT_STATUS_BAD_NETWORK_NAME"

Using smbclient with either either ntlm or kerberos, fails.

# /usr/local/samba/bin/smbclient -d9 //t4/fox -Ufox%f7
...
pm_process() returned Yes
lp_servicenumber: couldn't find homes

Homes are defined and exist per (testparm -vss|egrep -A 3 "homes|shares")
[homes]
        comment = Home Directories
        path = /s4/homes/%S

[shares]
        comment = Test Share
        path = /s4/shares
        read only = No

The folders were created and "chown 3000021 /s4/homes/fox" and "chmod -R 777 /s4/homes/"
# ls -l /s4
drwxrwxrwx  7 root  wheel  512 Feb  4 02:08 homes/
drwxr-xr-x  2 root  wheel  512 Feb  5 04:35 kits/
drwxr-xr-x  4 root  wheel  512 Feb  4 02:08 shares/

Samba4 is running correctly except accessing the [homes] section.

Before we rebuild Samba we delete /usr/local/samba/* then build using

./configure --enable-debug --enable-selftest --with-aio-support \
            --with-acl-support --with-sendfile-support --with-quotas -j2

/usr/local/samba/bin/samba-tool domain provision --realm=AS.LAN --domain=AS \
--adminpass=A1 --server-role=dc --host-ip=10.0.5.241 --debuglevel=2 \
--ldapadminpass=L1 --host-name=t4 --use-rfc2307 \
--function-level=2008_R2 --use-xattrs=yes --dns-backend=BIND9_FLATFILE

Is there anything that stands out requiring further investigation, or can someone suggest how I can dig deeper?

Regards, Dewayne.
