What configuration option is recommended for connecting to Active Directory for redundancy?

The recommended configuration option for connecting to Active Directory for redundancy involves defining domain controllers manually. By selecting specific domain controllers, you can ensure that the Identity Security Cloud has connections to multiple available controllers, thus providing a more resilient setup. This approach enables better control over the connection paths and allows for the inclusion of multiple domain controllers that can serve as backups. If one domain controller is down, the system can seamlessly switch to another one, ensuring continuous service availability and maintaining access to directory resources.

Using automatic domain controller selection, while convenient, may not provide the same level of control and redundancy since it could randomly choose a controller that may not be optimal or available. Additionally, relying on a single domain controller poses a significant risk; if that controller becomes unavailable, the system would lose its connection to Active Directory entirely. Configuring domain controllers after service initialization might lead to service interruptions and is not ideal, as the application would not have the expected redundancy right from the start.

Overall, the strategy of manually defining domain controllers aligns with best practices for achieving redundancy and reliability in Active Directory connections.
