I built the updates of PostgreSQL with patches for 1C into my repository RHEL-based.
I have updated samba to version 4.5.3 for Centos 7.
For Windows XP SP3 users need to add the param in /etc/samba/smb.conf:
ntlm auth = yes
You can add the repository and use it.
If you update from previous version, may check the database:
# samba-tool dbcheck
