@andy , maybe post the code so we can have look, i also setup the azure ad for backoffice and little issues . Sounds like the redirect maybe in correct to redirect back to where the user login from , if your case website/umbraco .

Maybe check what you have set

<add key="azureAd:redirectUrl" value="http://localhost:7518/umbraco" />

for example

Hi Andy, thanks for your answer, here are some code:

appSettings.config:

 <add key="owin:appStartup" value="UmbracoStandardOwinStartup" /> 

UmbracoStandardOwinStartup.cs:

public class UmbracoStandardOwinStartup : UmbracoDefaultOwinStartup
{

    /// <summary>
    /// Configures the back office authentication for Umbraco
    /// </summary>
    /// <param name="app"></param>
    protected override void ConfigureUmbracoAuthentication(IAppBuilder app)
    {

        base.ConfigureUmbracoAuthentication(app);

        app.ConfigureBackOfficeAzureActiveDirectoryAuth(
            tenant: ConfigurationManager.AppSettings["azureAd:tenantId"],
            clientId: ConfigurationManager.AppSettings["azureAd:clientId"],
            postLoginRedirectUri: ConfigurationManager.AppSettings["azureAd:redirectUrl"],
            issuerId: new Guid(ConfigurationManager.AppSettings["azureAd:tenantId"]));

    }
}

UmbracoADAuthExtensions.cs

public static class UmbracoADAuthExtensions
{

    public static void ConfigureBackOfficeAzureActiveDirectoryAuth(this IAppBuilder app, 
        string tenant, string clientId, string postLoginRedirectUri, Guid issuerId,
        string caption = "Active Directory", string style = "btn-microsoft", string icon = "fa-windows")
    {         

        var authority = string.Format(
            CultureInfo.InvariantCulture,
            "https://login.microsoftonline.com/{0}",
            tenant);

        var adOptions = new OpenIdConnectAuthenticationOptions
        {
            SignInAsAuthenticationType = Constants.Security.BackOfficeExternalCookieName,
            ClientId = clientId,
            Authority = authority,                
            RedirectUri = postLoginRedirectUri,
        };

        adOptions.BackchannelHttpHandler = new HttpClientHandler
        {
            UseProxy = true,
            Proxy = new WebProxy
            {
                Address = new Uri($"{ConfigurationManager.AppSettings["Our.ProxyServer"]}:{ConfigurationManager.AppSettings["Our.ProxyPort"]}"),
                UseDefaultCredentials = true
            }
        };


        adOptions.SetBackOfficeExternalLoginProviderOptions(
            new BackOfficeExternalLoginProviderOptions
            {
                AutoLinkOptions = new ExternalSignInAutoLinkOptions(
                    autoLinkExternalAccount: false,

                    defaultUserGroups: new[] { Constants.Security.EditorGroupAlias },

                    defaultCulture: null)
                    {
                        AllowManualLinking = true,

                        OnAutoLinking = (user, externalLogin) =>
                        {
                        },                      
                    },

                DenyLocalLogin = false,

                AutoRedirectLoginToExternalProvider = false
            });

        adOptions.ForUmbracoBackOffice(style, icon);            
        adOptions.Caption = caption;
        adOptions.AuthenticationType = string.Format(
            CultureInfo.InvariantCulture,
            "https://sts.windows.net/{0}/",
            issuerId);


        app.UseOpenIdConnectAuthentication(adOptions);

    }


}

I made the Azure Active Directory Settings like in the documentation. Must i define in AAD the allowed User-Groups?

thanks and kind regards, Andy

Hi Andy, thanks for your help. I have added a azure ad group with the Backoffice Users, but i get still an error after Login - i think this happen before i come back to umbraco (i'm stand on thiss url after insert the user/pw - https://login.microsoftonline.com/login.srf).

I think i must check the azure ad configuration again with our cloud team.

I will update this issue when i check this.

thanks and kind regards, andy
