Our DataMiner servers are joined to a domain and we usse Active Directory groups in DataMiner to manage  the diferent roles. When we add a existing group in DataMiner, all the users included in the group are well added in DataMiner. The issue is when we add a new user in a Active Directory group previously added to DataMine. The users don’t appear in DataMiner. If I delete the group in DataMiner and I add it again, the users are well added. Active Directory groups are supposedly updated every hour in DataMiner but it looks its not working fine.

What can be checked to find out what the problem might be?
