During the upgrade process (whith "make install") it somehow assumes the samba domain ends at the first dot instead of using the domain name defined in the "workgroup" variable of smb.conf.
We have classicupgrade-d a domain containing a "." character like "IPPOLITO.DOM", with DNS domain "enterprise.it".
It works beautifully until we upgrade samba with the usual "make install". (yes, we stop the daemons and do the proper backups first)
fter the upgrade the windows domain (and Kerberos realm) is IPPOLITO instead of IPPOLITO.DOM and the DNS domain is DOM.ENTERPRISE.IT instead of ENTERPRISE.IT.
