Oracle linux 8.5 cant join Samba 4.15.5 to Active Directory

Hello!

Can somebody help me? I cant  join Samba 4.15.5 to Active Directory (AD) from my Oracle Linux 8.5

I join the linux in Active directory. Now i can see AD users. For example:

id user@my_domain

I take info about my user from AD.

My Samba config:

[global]
  netbios name = SERVERNAME
  idmap config MYDOMAIN : range = 10000-20000
  winbind enum users = yes
  winbind gid = 10000-20000
  workgroup = WORKGROUP
  winbind enum groups = yes
  preferred master = no
  winbind separator = +
  encrypt passwords = yes
  dns proxy = no
  realm = MYDOMAIN
  security = ADS
  map to guest = Never
  log file = /var/log/samba/log.%m
  max log size = 50
  server min protocol = SMB2
  server max protocol = SMB3

[SharingName]
  path = /Data/Temp
  valid users = @"MYDOMAIN+user"
  guest ok = no
  browsable = yes
  writable = no
