[Samba] azure ad connect timeout

[Heinz Hölzl]

Hi,

we use "Azure AD connect" to sync users from the samba-AD to office365.


The synchronization worked fine for about 2 years. 

Now I get an error when I start a full import:

stopped-connectivity - failed-search - timeout - Errorcode: 0x55


I'm not sure if it has happened since upgrading from 4.10.5 to 4.12.6
or if it is due to the increased amount of users.

I have to do a fullsync because more containers have been added for
sync.

Any ideas?


my system: 
4 DCs with samba 4.12.6 running on ubuntu 20.04


Regards, 
Heinz

p.s. 
it wasn't my idea to use office365 ;-)
