[Samba] Setting 'unix charset' kills the samba share

Hello,

When I define


*unix charset = ISO-8859-1*

in *smb.conf*, it does not work. When I comment it, the share works fine.
However, we need to define the charset...

When unix charset is


Here is the global section of smb.conf

[global]

  workgroup = COMPANY
  realm = COMPANY.COM
  security = ADS


   winbind use default domain = true
   winbind offline logon = true

   idmap config * : backend = tdb
   idmap config * : range = 0-499
   idmap config COMPANY:backend = ad
   idmap config COMPANY:schema_mode = rfc2307
   idmap config COMPANY:range = 500-20000
   idmap config COMPANY:unix_nss_info = yes

   encrypt passwords = yes

   template shell = /bin/bash
   template homedir = /home/%U

   log level = 5
   log file = /var/log/samba/log.%m
   strict locking = no
   unix extensions = no
   dos charset = cp850

   # need to comment out this to get it to wrok

   unix charset = ISO-8859-1


We are running smbd 4.8.3. Previously, we had  4.2.3 and  this

     unix charset = ISO8859-1

was ok.   I found this posting  :
https://www.ibm.com/developerworks/community/forums/html/topic?id=bcba0bd5-2b44-454a-8d56-fea725b3974e

saying that we should use:

     unix charset = ISO-8859-1

 but it does not work for us.

Any idea ?

Thanks

Gilbert

[Samba] Setting 'unix charset' kills the samba share

This is on Centos 7.4

I see this when I start smbd :

[root at zinc samba]# systemctl status smb.service

I changed the log level to 3 to reduce the size. I see this in  log.smbd:

This seems interesting:

But what values are supported ?

Where did you get the Samba packages from and what actual Samba
packages do you have installed ?

Everything seems to be there, have you tried 'testparm' ?
Is locales set up correctly on the OS
what Samba binaries are running ?

The last things I can think of to do now are:
run 

testparm -v | grep 'dos charset'

and

testparm -v | grep 'unix charset'

(with neither in smb.conf) to see what the defaults are.

Turn up logging to see if anything else pops out.

Stop Samba, then manually start the Samba binaries (in a terminal) with
smbd -D and winbindd -D, see if that makes any difference

If all else fails, move from Canada to England, we don't have
accents ;-)
