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

Mon Jan 14 20:28:07 UTC 2019

This is on Centos 7.4

I see this when I start smbd :

[root at zinc samba]# systemctl status smb.service
* smb.service - Samba SMB Daemon
   Loaded: loaded (/usr/lib/systemd/system/smb.service; disabled; vendor
preset: disabled)
   Active: failed (Result: exit-code) since Mon 2019-01-14 15:19:01 EST;

           man:samba(7)
           man:smb.conf(5)

 Main PID: 9214 (code=exited, status=1/FAILURE)
   Status: "daemon failed to start: Samba cannot setup ep pipe"
    Error: 13 (Permission denied)

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

This seems interesting:

../lib/util/charset/convert_string.c:391(convert_string_talloc_handle)
  convert_string_talloc: Conversion not supported.

But what values are supported ?
