LDAP Synchronization, changes only, how to reset change date

[skushnerenko]

Our Alfresco instance was set to synchronize with AD  changes only.

synchronization.synchronizeChangesOnly=true

ldap.synchronization.personDifferentialQuery=(&(objectclass\=user)(userAccountControl\:1.2.840.113556.1.4.803\:\=512)(!(whenChanged<\={0})))

After some trouble with server infrastracture, last change was set as  Oct 4, 2037, so in alfresco.log we have

2019-06-26 14:49:23,391 INFO [org.alfresco.repo.security.sync.ChainingUserRegistrySynchronizer] [localhost-startStop-1] Retrieving users changed since Oct 4, 2037 7:33:33 PM from user registry 'ldap1'

How to reset this date to current?

I have tried to restart alfresco in Full synchronization mode with

synchronization.synchronizeChangesOnly=false

All users were synchronized but after returning to synchronizeChangesOnly mode and restarting alfresco, synchronization started since 2037 year again.

Hi:

Have both your AD server and Alfresco server the correct date ?

Regards.

--C.

Alfresco has correct date.

As for AD server, I suppose it should be correct, I am waiting confirmation from admin.

Currently the date both on Alfresco server and on AD server is correct. Alfresco had been restarted yesteday, but synchronization is still retrieving users since 2037
