Tenant impersonation & User impersonation

User impersonation allows you to temporarily sign in as a different user in your tenant's users. This article introduces how to enable impersonation in ABP. Impersonation is enabled by defautl in ABP v5.0 and above.

Introduction

In some cases, users need to sign in as another user and perform operations on behalf of the target user without sharing the target user's password.

How to enable impersonation feature?

If your ABP version is lower than 5.0, you can implement the impersonation feature by following the steps below.

Please remember to configure the ImpersonationTenantPermission and ImpersonationUserPermission permissions!!!

MVC

public override void ConfigureServices(ServiceConfigurationContext context)
{
    var configuration = context.Services.GetConfiguration();

    //For impersonation in Saas module
    context.Services.Configure<AbpSaasHostWebOptions>(options =>
    {
        options.EnableTenantImpersonation = true;
    });

    //For impersonation in Identity module
    context.Services.Configure<AbpIdentityWebOptions>(options =>
    {
        options.EnableUserImpersonation = true;
    });

    context.Services.Configure<AbpAccountOptions>(options =>
    {
        //For impersonation in Saas module
        options.TenantAdminUserName = "admin";
        options.ImpersonationTenantPermission = SaasHostPermissions.Tenants.Impersonation;

        //For impersonation in Identity module
        options.ImpersonationUserPermission = IdentityPermissions.Users.Impersonation;
    });
}
