-> For user and application authentication, we recommend using the [Kusto client libraries](../api/client-libraries.md).

-When the authorization of a user or application principal is checked, the system first checks for an explicit role assignment permitting the specific action. If no such role assignment exists, the system then analyzes the principal's membership across all groups that could potentially authorize the action. If the principal is confirmed to be a member of any of these groups, the requested action is authorized. Otherwise, if the principal is not a member of any such groups, the action doesn't pass the authorization check and the action isn't allowed.

+### Force group membership refresh
+
+Principals can force a refresh of group membership information. This capability is useful in scenarios where just-in-time (JIT) privileged access services, such as Microsoft Entra Privileged Identity Management (PIM), are used to obtain higher privileges on a resource.
+
+#### Refresh for a specific group
+
+Principals can force a refresh of group membership *for a specific group*. However, the following restrictions apply:
+
+* A refresh can be requested up to 10 times per hour per principal.
+* The requesting principal must be a member of the group at the time of the request.
+
+The request results in an error if either of these conditions aren't met.
+
+To reevaluate the current principal's membership of a group, run the following command:
+
+```kusto
+.clear cluster cache groupmembership with (group='<GroupFQN>')
+```
+
+Use the group's fully qualified name (FQN). For more information, see [Referencing Microsoft Entra principals and groups](../management/reference-security-principals.md#referencing-microsoft-entra-principals-and-groups).
+
+#### Refresh for other principals
+
+A privileged principal can request a refresh **for other principals**. The requesting principal must have [AllDatabaseMonitor](role-based-access-control.md) access for the target service. Privileged principals can also run the previous command without restrictions.
+
+To refresh another principal’s group membership, run the following command:
+
+> In the following command, replace `<PrincipalFQN>` with your own principal fully qualified name (FQN) and `<GroupFQN>` with your own group FQN. For more information, see [Referencing Microsoft Entra principals and groups](../management/reference-security-principals.md#referencing-microsoft-entra-principals-and-groups).
+
+```kusto
+.clear cluster cache groupmembership with (principal='<PrincipalFQN>', group='<GroupFQN>')
