[Pkg-samba-maint] Bug#816301: samba 2:4.3.3 refuses to start

[Francesco Potortì]

I identified the problem source: this version of Samba does not accept
"security = share" any more and the /etc/init.d/nmbd script fails.  The
reason is that:

# samba-tool testparm --parameter-name="server role"
WARNING: Ignoring invalid value 'share' for parameter 'security'
ERROR: Unable to load default file

however, this specific output is not checked for in /etc/init.d/nmbd,
which fails without giving any meaningful error, and nothing meaningful
is logged either.

In short, before upgrading Samba, a check of configuration validity
should be done and upgrading should be stopped if "security = share" is
found in /etc/smb.conf.

By the way, the configuration check could also warn about deprecated
verbs in the configuration file.
