Can't join domain

[dlaurenz]

i have a problem with the newest firmware.... since yesterday domain access does not work, so i tried to rejoin, but this also fails. i joined a fresh install debian sucessfully to the domain to make sure the dc are not the problem and have 2 other qnaps which work perfectly in the samba 4 ad domain....one of them has QTS 4.2 the other one the newest firmware

here's the log:

my setup

3x Samba 4.7 DC controllers
3x QNAP, 2 of them run perfectly

Firmware of the one which is unable to join QTS 4.3.3.0361.

Hi and welcome to the forum.

Please don't post the same problem in multiple topics. I've removed your duplicate post.

sorry - i thought as repley it might not be seen....

this is strange - i tried a readonly dc - and it worked to join - a more complex variant, but ok...
any explanation?

readonly dc means,, i configured the qnap as readonly dc
