[Samba] azure ad connect timeout

[Heinz Hölzl]

Hi,


I have downgraded a DC to version 4.10.7, 
and so the fullimport and fullsync to the "azure AD" worked as
expected.

when i sync from a DC with 4.12.6 the sync fails, alway with the
errors:
stopped-connectivity - failed-search - timeout - Errorcode: 0x55


when i sync from a DC with 4.10.7 the sync works fine.


So I have to run at least 1 DC with the old version 4.10.7 and can not
upgrade.



Is there a way to fix this?


Regards,
Heinz
