Security Software

I hope someone can help. We currently have a sync between AD - OID where users are created in AD then authenicated for OID. However since Sunday 2pm the sync between AD - OID has stopped working. I beleive this is due to an expired certificate (I think from AD). However I am not certian. Greatful for any advice. Additional details below.
