[Samba] Samba 4.6.2 member server errors

[me at tdiehl.org]

Hi,

I have 2 samba AD DC's running 4.7.0 and 2 member servers running 4.6.2.

Everything seems to be working OK except that I see the following errors
over and over again in the winbind log on one of the member servers:

[2017/10/12 00:53:52.351095,  2] ../auth/kerberos/kerberos_pac.c:96(check_pac_checksum)
   check_pac_checksum: PAC Verification failed: Decrypt integrity check failed (-1765328353)
[2017/10/12 00:53:52.871160,  2] ../auth/kerberos/kerberos_pac.c:96(check_pac_checksum)
   check_pac_checksum: PAC Verification failed: Decrypt integrity check failed (-1765328353)
[2017/10/12 00:53:54.588468,  2] ../auth/kerberos/kerberos_pac.c:96(check_pac_checksum)
   check_pac_checksum: PAC Verification failed: Decrypt integrity check failed (-1765328353)

Can someone tell me what this means and if I should troubleshoot this further?

My Google foo has not been helpful.

Regards,
