We are using FreeIPA for Linux accounts and a Windows DC for Windows 
Users were able to access their Linux file systems from Windows using 
their windows user name and password.

After upgrading samba from samba-4.10.16-7.el7_9.x86_64 to 
samba-4.10.16-18.el7_9.x86_64 users cannot authenticate and I get the 
following error message:
   check_account: Failed to convert SID 
S-1-5-21-xxxxxxx-xxxxxxx-xxxxxxx-1158 to a UID (dom_user[DOMAIN\username])

Winbind is still running

My smb.conf:

        netbios name = HOSTNAME
        security = ADS
        workgroup = DOMAIN
        realm = DOMAIN.FULL.NAME

        socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 
        use sendfile = true
        dns proxy = no

        log file = /var/log/samba/%m.log
        max log size = 50
        log level = 1

        client signing = required
        server signing = auto

         comment = TMP-Disk
         public = yes
         path = /tmp
         browsable = Yes
         read only = No

Nothing else updated or changed.
What do I miss? This setup was working for years..

Thank you in advance!
