[Bug 1583324] Re: Samba won't start when an include statement in smb.conf has a variable substitution

Tue Jul 17 19:13:57 UTC 2018

This seems to be working in 4.3.11 that is in xenial:
root at xenial-samba-dynamic-include:~# testparm -s
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

Can't find include file /etc/samba/smb.conf.
Loaded services file OK.
WARNING: The 'netbios name' is too long (max. 15 chars).

# Global parameters

	server role = standalone server

	pam password change = Yes
	passwd program = /usr/bin/passwd %u
	passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
	unix password sync = Yes
	syslog = 0

	idmap config * : backend = tdb
	include = /etc/samba/smb.conf.
root at xenial-samba-dynamic-include:~# echo $?
0

Notice how it didn't expand %U, and the include file was /etc/samba/smb.conf. (ending dot). Restart works:
root at xenial-samba-dynamic-include:~# systemctl restart smbd nmbd
root at xenial-samba-dynamic-include:~# systemctl status smbd nmbd

Are you also seeing this behavior now?

Title:
  Samba won't start when an include statement in smb.conf has a variable
  substitution

Status in samba package in Ubuntu:
  Incomplete

Bug description:
  Samba refuses to start when the smb.conf file contains an include line
  with a variable substitution like "include = /etc/samba/smb.conf.%U"

  According to the man page for smb.conf, all but a few specific
  variable substitutions should work.

  include (G)

             This allows you to include one config file inside another.
  The file is included literally, as though typed in place.

             It takes the standard substitutions, except %u, %P and %S.

             The parameter include = registry has a special meaning: It does not include a file named registry from the current working directory, but
             instead reads the global configuration options from the registry. See the section on registry-based configuration for details. Note that
             this option automatically activates registry shares.

             Default: include =

             Example: include = /usr/local/samba/lib/admin_smb.conf

  It is probably related to this bug in samba:
