Bug 2062117

Samba 4.15 introduces several changes to command-line utilities, which can break existing scripts, Cron jobs, etc. This deserves a separate release note and should not be hidden in the Samba rebase release note.


From https://www.samba.org/samba/history/samba-4.15.0.html:


Improved command line user experience
-------------------------------------

Samba utilities did not consistently implement their command line interface. A
number of options were requiring to specify values in one tool and not in the
other, some options meant different in different tools.

These should be stories of the past now. A new command line parser has been
implemented with sanity checking. Also the command line interface has been
simplified and provides better control for encryption, signing and kerberos.

Previously many tools silently ignored unknown options. To prevent unexpected
behaviour all tools will now consistently reject unknown options.

Also several command line options have a smb.conf variable to control the
default now.

All tools are now logging to stderr by default. You can use "--debug-stdout" to
change the behavior. All servers will log to stderr at early startup until logging
is setup to go to a file by default.

### Common parser:

Options added:
--client-protection=off|sign|encrypt

Options renamed:
--kerberos       ->    --use-kerberos=required|desired|off
--krb5-ccache    ->    --use-krb5-ccache=CCACHE
--scope          ->    --netbios-scope=SCOPE
--use-ccache     ->    --use-winbind-ccache

Options removed:
-e|--encrypt
-C removed from --use-winbind-ccache
-i removed from --netbios-scope
-S|--signing


### Duplicates in command line utils

ldbadd/ldbdel/ldbedit/ldbmodify/ldbrename/ldbsearch:
-e is still available as an alias for --editor,
   as it used to be.
-s is no longer reported as an alias for --configfile,
   it never worked that way as it was shadowed by '-s' for '--scope'.

ndrdump:
-l is not available for --load-dso anymore

net:
-l is not available for --long anymore

sharesec:
-V is not available for --viewsddl anymore

smbcquotas:
--user        ->    --quota-user

nmbd:
--log-stdout  ->    --debug-stdout

smbd:
--log-stdout  ->    --debug-stdout

winbindd:
--log-stdout  ->    --debug-stdout
