[Samba] SPN problem after update 4.13.8 to 4.13.14

[Nikita Druba]

Hi!

I'm use FreeBSD 12.2 and samba 4.13.8 as DC. All worked fine many years, 
but after update to version 4.13.14, I have some troubles with issuing 
kerberos tickets for ldap service at my DC. When I downgrades samba 
back, all work fine again.

Some strings from log.samba:

[2021/11/16 09:22:47.366807,  3] 
./../source4/auth/kerberos/krb5_init_context.c:80(smb_krb5_debug_wrapper)

When I check SPNs for my DC:

# samba-tool spn list dc$
dc$
User CN=dc,OU=Domain Controllers,DC=samdom,DC=local has the following 
servicePrincipalName:
          HOST/DC
          HOST/dc.samdom.local
          GC/dc.samdom.local/samdom.local

          HOST/dc.samdom.local/SAMDOM
          ldap/dc.samdom.local/SAMDOM
          ldap/dc.samdom.local
          HOST/dc.samdom.local/samdom.local
          ldap/dc.samdom.local/samdom.local

          ldap/dc.samdom.local/DomainDnsZones.samdom.local
          ldap/dc.samdom.local/ForestDnsZones.samdom.local

What is wrong in my case?

Tnax in advance.
