Error with LDAP Sync

LDAP sync not working. We have two systems, one for Assets and one for Trend Micro. All users from the LDAP were syncing fine, but since two weeks the LDAP says sync is successful but, no data is coming through. no new users which we created in AD are coming through.

Can someone advise what can be done to fix this?

Both the Systems should have some error message when the Sync failed.  Are you able to share the error message...

HI Antz,

As mentioned the sync does not say failed. It says successful but, there is no data pulled. The new users who are created in the new OU are not pulled across.

Does it matter if we used to have an SSL certificate which has expired? We have configured the LDAP to use port 389 and not using LDAPS.

If it says successful the SSL Certificate does not matter.  Was there any change in the OU Structure in your AD?  Probably it is just syncing the wrong OU which does not contain your new users.

It was the filter setup on our system. Removed the filter and all was working.
