[Samba] smbd do not start

[Rommel Rodriguez Toirac]

Hello all;

I am installing samba4 (version 4.9.5) on Debian 10.5 to use it as a member of a samba4 AD DC domain (version 4.11.4). I am following the guide https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Domain_Member but I am having problems starting samba.

 So far I have installed the necessary packages listed here https://wiki.samba.org/index.php/Package_Dependencies_Required_to_Build_Samba

 I have modified /etc/krb5.conf

###
[libdefaults]
       dns_lookup_realm = false
       dns_lookup_kdc = true
       default_realm = GTM.ONAT.GOB.CU
###

The configuration of /etc/resolv.conf looks like this:

###
search gtm.onat.gob.cu
nameserver 192.168.41.17
###

and /etc/samba/smb.conf

###
[global]
  workgroup = ATGTM00
  security = ADS
  realm = GTM.ONAT.GOB.CU

  winbind refresh tickets = Yes
  vfs objects = acl_xattr
  map acl inherit = Yes
  store dos attributes = Yes

  dedicated keytab file = /etc/krb5.keytab
  kerberos method = secrets and keytab
  winbind use default domain = yes
  username map = /etc/samba/user.map

 log file = /var/log/samba/%m.log
 log level = 1   

 idmap config * : backend = tdb
 idmap config * : range = 3000-7999
 idmap config ATGTM00 : backend = rid
 idmap config ATGTM00 : range = 10000-999999

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

But when I try to start smbd it gives me this error:

$ sudo systemctl status smbd.service -l

 What could I be doing wrong?
