How to allow multiple clients to share the same logout?

[kevinchalet]

Hi,

How to allow multiple clients to share the same logout?

This scenario requires single sign-out, which is not currently supported by OpenIddict. Backchannel logout may be supported in a future version (see openiddict/openiddict-core#2175), but it will only work with server-side web applications.

As an alternative, you can revoke access tokens issued to specific clients from your end session endpoint (note: OpenIddict 6.0 will introduce new APIs to revoke authorizations and tokens attached to a specific client or subject more efficiently) and use the introspection endpoint to query the current status of a token from time to time, which allows detecting whether a token was revoked or not.

[feededit]

As you know, your answer leads to two questions.
If revoke-access-tokens refers to log out and is a function of version 4.0 or lower, please guide me on how to revoke access tokens.
I will try to upgrade my project by downloading from 4.0 to 6.0 at ruget and then modifying project code. Is this possible?

[kevinchalet]

Here's how you can revoke all the valid access tokens attached to a specific user directly from the logout endpoint (these APIs are already in OpenIddict 4 and 5):

[HttpGet("~/connect/logout")]
public IActionResult Logout() => View();

[ActionName(nameof(Logout)), HttpPost("~/connect/logout"), ValidateAntiForgeryToken]
public async Task<IActionResult> LogoutPost()
{
    var result = await HttpContext.AuthenticateAsync(OpenIddictServerAspNetCoreDefaults.AuthenticationScheme);
    if (result is not { Succeeded: true })
    {
        return SignOut(
            authenticationSchemes: OpenIddictServerAspNetCoreDefaults.AuthenticationScheme,
            properties: new AuthenticationProperties
            {
                RedirectUri = "/"
            });
    }

    var subject = result.Principal.GetClaim(Claims.Subject) ?? throw new InvalidOperationException();

    await foreach (var token in _tokenManager.FindBySubjectAsync(subject))
    {
        if (await _tokenManager.GetTypeAsync(token) is TokenTypeHints.AccessToken)
        {
            await _tokenManager.TryRevokeAsync(token);
        }
    }

    // Ask ASP.NET Core Identity to delete the local and external cookies created
    // when the user agent is redirected from the external identity provider
    // after a successful authentication flow (e.g Google or Facebook).
    await _signInManager.SignOutAsync();

    // Returning a SignOutResult will ask OpenIddict to redirect the user agent
    // to the post_logout_redirect_uri specified by the client application or to
    // the RedirectUri specified in the authentication properties if none was set.
    return SignOut(
        authenticationSchemes: OpenIddictServerAspNetCoreDefaults.AuthenticationScheme,
        properties: new AuthenticationProperties
        {
            RedirectUri = "/"
        });

}

Alternatively, you can also just revoke the authorizations, which will automatically cause the associated tokens to be rejected when trying to introspect them:

var subject = result.Principal.GetClaim(Claims.Subject) ?? throw new InvalidOperationException();

// More efficient way of doing it, but OpenIddict 6.0+-only:
// await _authorizationManager.RevokeBySubjectAsync(subject);

// Usable in previous versions of OpenIddict:
await foreach (var authorization in _authorizationManager.FindBySubjectAsync(subject))
{
    await _authorizationManager.TryRevokeAsync(authorization);
}

// Ask ASP.NET Core Identity to delete the local and external cookies created
// when the user agent is redirected from the external identity provider
// after a successful authentication flow (e.g Google or Facebook).
await _signInManager.SignOutAsync();

// Returning a SignOutResult will ask OpenIddict to redirect the user agent
// to the post_logout_redirect_uri specified by the client application or to
// the RedirectUri specified in the authentication properties if none was set.
return SignOut(
    authenticationSchemes: OpenIddictServerAspNetCoreDefaults.AuthenticationScheme,
    properties: new AuthenticationProperties
    {
        RedirectUri = "/"
    });

Once it's in place, enable the introspection endpoint in your server configuration and grant your client the introspection endpoint permission. You'll then be able to use OpenIddictClientService.IntrospectTokenAsync() (or any other client supporting the OAuth 2.0 introspection endpoint) to determine if the token is still valid or not at regular intervals:

// If that call fails and throws an exception, the access token is no longer valid.
_ = await _service.IntrospectTokenAsync(new()
{
    Token = "your access token",
    TokenTypeHint = TokenTypeHints.AccessToken
});

The above source works normally in 5.0, but an error of unknown cause occurred in my project.

After performing several tests, I confirmed that my project version was 3.1.1 for the server and 4.0 for the client.

I would like to solve this problem by downloading the server's openiddick library as 5.X from ruget and using the server project code as is.

This approach would likely make my project seriously complex.

Server openiddick library: 5.X (or 4.X)
Server code: Code used in 3.1.1 (or modify only the necessary parts)
Client openiddick library and code: 4.0

Is it possible?

[kevinchalet]

Using different versions of the OpenIddict packages in the same application is not supported but if you're using the OpenIddict server and client in different projects, it shouldn't be a problem.

That said, both OpenIddict 3.x and 4.x are no longer supported so I strongly encourage you to update all your projects to 5.x:

• https://documentation.openiddict.com/guides/migration/30-to-40
• https://documentation.openiddict.com/guides/migration/40-to-50

[feededit]

thank you

I would like to upgrade to 5.x, but I will upgrade to 4.x.
For 6.x, I hope there will be an upgrade guide for 4.x

[feededit]

Migration from 4.0 to 5.0

I will download and use the 5.0 sample source.
Will my existing 4.X databases be automatically upgraded?
If doesn't upgrade automatically, can I do it manually in SSMS?

Added properties
Table	Column name	Type	Nullable
OpenIddictApplications	ApplicationType	string	Yes
OpenIddictApplications	JsonWebKeySet	string	Yes
OpenIddictApplications	Settings	string	Yes
Renamed properties
Table	Old column name	New column name
OpenIddictApplications	Type	ClientType

Velusia in openiddict-samples-dev 5.X version appears following error.
When a client logs in, the logged in client is logg off.
When VelusiaA.com log in, VelusiaB.com log off, and when VelusiaB.com log in, VelusiaA.com log off.
test is result from two clients, so I don't know if all clients are log off.

[kevinchalet]

Will my existing 4.X databases be automatically upgraded?

Nope. If you use EF Core and its built-in migrations feature, add a new migration after updating the packages and execute it: it will update your database.

Velusia in openiddict-samples-dev 5.X version appears following error.

Hum, what error exactly?

[feededit]

I created two Volusia clients. And when I log in one of them, the other client logs off.

I created two Volusia clients. And when I log in one of them, the other client logs off.

Weird. Are your two clients hosted on the same domain (e.g localhost)? If so, do you use different cookie names?

[feededit]

I am in testing. So it's localhost.

[kevinchalet]

It's possible the ASP.NET Core authentication cookies are colliding. Try setting a different name in one of your clients via services.ConfigureApplicationCookie(...) if you're using ASP.NET Core Identity or in your services.AddAuthentication().AddCookie(...) call if you're not using Identity.

[feededit]

thank you. I'll let you know the results after testing it.

[kevinchalet]

My pleasure! ❤️

[feededit]

It worked out well. thank you.

However, single sign-out does not work.

VelusiaServer.com VelusiaClientA.com VelusiaClientB.com is logged in. When VelusiaClientA.com logs out, VelusiaServer.com and VelusiaClientA.com log out, but VelusiaClientB.com remains logged in.

[kevinchalet]

Did you implement this part in your client app? Remember it's not real "single sign-out", you need to poll the token status at regular intervals using introspection:

Once it's in place, enable the introspection endpoint in your server configuration and grant your client the introspection endpoint permission. You'll then be able to use OpenIddictClientService.IntrospectTokenAsync() (or any other client supporting the OAuth 2.0 introspection endpoint) to determine if the token is still valid or not at regular intervals:

// If that call fails and throws an exception, the access token is no longer valid.
_ = await _service.IntrospectTokenAsync(new()
{
    Token = "your access token",
    TokenTypeHint = TokenTypeHints.AccessToken
});

[feededit]

I'm not trying to complete single sign-out.
I am satisfied as long as when one client logs out, the other clients also log out. (Only two clients.)

I'm very interested in log out other clients with the cookie name I just resolved.

Couldn't this issue be resolved by log out other clients using the cookie name?

[kevinchalet]

I'm not trying to complete single sign-out.

Well, one client or 50, it doesn't change anything, it's still single sign-out, which requires a very specific implementation 😄

Couldn't this issue be resolved by log out other clients using the cookie name?

Well, it offers a limited level of security since a user can copy the cookies and replay them (they are not "invalidated"). I wouldn't really recommend it.

[feededit]

Sorry but I still don't understand.

introspection endpoint : server
introspection endpoint permission : client
OpenIddictClientService.IntrospectTokenAsync() : ?
IntrospectTokenAsync : ?

What do I need to do to know introspection?

[kevinchalet]

OpenIddictClientService.IntrospectTokenAsync() must be used in your client applications to query the current status of a token and invalidate their authentication cookie.

One simple option is to do that in the CookieAuthenticationEvents.OnValidatePrincipal event: if OpenIddictClientService.IntrospectTokenAsync() throws an exception (indicating it's no longer valid), call context.RejectPrincipal() to reject the user principal.

[feededit]

enable the introspection endpoint in your server configuration and grant your client the introspection endpoint permission.

You need to add options.SetIntrospectionEndpointUris("connect/introspect") in the server options and update your client applications to give them the OpenIddictConstants.Permissions.Endpoints.Introspection permission.

If it still doesn't work, share your logs and I'll take a look.

[feededit]

"connect/introspect"

You must provide code that handles the server's Introspect endpoint.

[feededit]

The server options appear to be incorrect.
The result of the code below is not received.

You must provide code that handles the server's Introspect endpoint.

Introspection requests are handled for you by OpenIddict itself: you don't need to provide an action for it.

[feededit]

I tested it with just the option settings, but it didn't work.
How do I test whether option settings are correct?
If I add the code below, will OpenIddict itself be ignored?

        [HttpGet("~/connect/introspect")]
        [HttpPost("~/connect/introspect")]
        public IActionResult Introspect()
        {
            return Ok(new { active = true });
        }

The token isn't attached to the introspection request, most likely because var accessToken = await HttpContext.GetTokenAsync("access_token"); returns null.

(I'll add a null check to make debugging easier, since it's not legal to send an introspection request without a token attached anyway)

[feededit]

The token isn't attached to the introspection request, most likely because var accessToken = await HttpContext.GetTokenAsync("access_token"); returns null.

The fundamental problem is that the code below does not read the access token.
What is the correct code to read the access token ?

     var accessToken = await HttpContext.GetTokenAsync("access_token");

[feededit]

BackchannelAccessToken is read. But it was rejected by the server.

                    var accessTokenClaim = await HttpContext.GetTokenAsync(OpenIddictClientAspNetCoreConstants.Tokens.BackchannelAccessToken);

[kevinchalet]

No, I really meant the logs of the authorization server: the OAuth 2.0 introspection specification requires returning active = false instead of a proper OAuth 2.0 error when the introspection request cannot be served to reduce token scanning attacks (which is very stupid, IMHO): this means that you'll never get any useful information just by looking at the client logs: you need the server logs to investigate further.

You didn't add the introspection endpoint permission...

[feededit]

You didn't add the introspection endpoint permission...

I won't know how unless you tell me.

[kevinchalet]

I won't know how unless you tell me.

👇🏻

and update your client applications to give them the OpenIddictConstants.Permissions.Endpoints.Introspection permission.

[feededit]

It works fine.
Nice work, as always.
Please close this issue.

Well, to be honest, it's a workaround, but it should work reliably for the time being 😄

4.x client can't connect to 5.X server?

It can, but you can't use the OpenIddict 5.x packages with a database creating using OpenIddict 4x if it hasn't been updated to use the 5.x schema using EF Core migrations.

[feededit]

Let's make the client 5.x.
