What action can an administrator take to efficiently control the synchronization of users in Active Directory?

Applying a specific LDAP filter in the existing Active Directory User Directory Connector (UDC) allows an administrator to efficiently control the synchronization of users. This is because LDAP filters enable targeted access to specific subsets of users or groups within Active Directory, rather than syncing all users indiscriminately. By using a tailored filter, an administrator can synchronize only those user accounts that are necessary, thus improving performance and reducing the load on the server.

This selective approach helps in managing the user base effectively, particularly in large organizations where numerous accounts may exist, resulting in a more streamlined synchronization process. It also enhances the security posture by ensuring that only the appropriate users are included in Qlik Sense, avoiding any unnecessary exposure of inactive or irrelevant accounts.

Other options, while they may seem viable, do not offer the same level of control or efficiency. For example, limiting the number of entities to sync manually may become cumbersome and prone to error; utilizing a separate synchronization schedule could lead to complexity in tracking and managing synchronizations; and increasing server resources, while potentially beneficial, does not address the fundamental issue of targeting specific user groups or accounts for synchronization.
