What is a potential reason for the Okta Active Directory Agent to fail to connect after startup?

The reason the Active Directory service account having insufficient administrator permissions is a potential cause for the Okta Active Directory Agent failing to connect after startup lies in the permissions required for the agent to operate effectively. The Okta Active Directory Agent requires sufficient permissions to authenticate to Active Directory, query user and group information, and perform synchronization tasks. If the service account does not have the necessary administrative privileges, it will be unable to perform these essential functions, resulting in connection failures.

Furthermore, the context of the other options can provide additional understanding. While installing the Okta Agent on a domain-joined machine or running it on a non-domain machine could potentially affect its operations, the key factor is the permissions of the service account, as this directly impacts the agent's ability to interact with Active Directory. If Active Directory is not properly configured, it could also lead to connection issues; however, proper permissions would still be essential regardless of the configuration status. Thus, the permission level of the service account is critical for the successful connectivity and functionality of the Okta Active Directory Agent.
