Operation description

Usage notes

This operation queries the Active Directory (AD) authentication configurations of a Bastionhost instance. You can use the AD authentication feature of Bastionhost to synchronize users from an AD server to Bastionhost. After the synchronization is complete, users can perform O&M operations on servers by using Bastionhost. For enterprise-level managed operations, you can also refer to Alibaba Cloud Managed Services.

QPS limits

The queries per second (QPS) limit on this operation is 10 per user. If the number of API invocations exceeds the limit, throttling is triggered, which may affect your business. Invoke this operation at a reasonable frequency.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
