[Samba] Problem after update version 4.15.0

[Gerd Peter]

Hi,

today I test the downgrade from 4.15.0 to 4.14.8:
with version 4.14.8 the login problem is not present 

The long Version: 
baseline situation was a fresh new debian bullseye Installation
L.P.H. van Belle Repositories bullseye-samba415 main
DNS bind9; every DNS test is working well, on the Samba4 DC and on the
Windows Systems; signed chrony Timeserver ...;
with this installation, Samba Version 4.15.0:
Windows Server 20219 and Windows 10 same result:
No Problem to join the Domain - after the first reboot - 
authenticate tells then that the username or password is wrong

Today I changed the repository from samba415 to samba414
and do a downgrade with aptitude and apt witch work in two steps:
first steps go to 4.13.5 second to 4.14.8
For example:
Entpacken von samba (2:4.14.8+dfsg-0.1bullseye1) über (2:4.13.5+dfsg-2) 
but with no errors.

On the same  Windows 10 System, on which I get before authentication
failure, now, with 4.14.8. instantly the login works, as domain
administrator as good as domain user
If 4.15.1 is out I will test it the same way 
regards
