Umbraco :: Catching or Extending User Login

Question

I am trying to catch the login event of Umbraco Users (login in the CMS).

I have tried to extend from MembersMembershipProvider and override the ValidateUser method. I also changed the web.config to use my class. When i put a breakpoint in this overrited method it doesnt stop and logsin the user as usual.

public class CustomUmbracoMembershipProvider : Umbraco.Web.Security.Providers.UsersMembershipProvider
{
    public override bool ValidateUser(string username, string password)
    {
        return base.ValidateUser(username, password);
    }
}

Thanks in advance.

As Jannik said, Umbraco uses ASP.NET Identity in the latest couple of versions, so the MembershipProvider is not used to validate and authenticate the user anymore.

So after a couple hours of research, i found a workaround solution:

1º - Create a custom UserManager, and override the method CheckPasswordAsync:

public class CustomBackOfficeUserManager : BackOfficeUserManager
{
    public CustomBackOfficeUserManager(
        IUserStore<BackOfficeIdentityUser, int> store,
        IdentityFactoryOptions<BackOfficeUserManager> options,
        MembershipProviderBase membershipProvider) :
        base(store, options, membershipProvider)
    {
    }

    /// <summary>
    /// Returns true if the password is valid for the user
    /// </summary>
    /// <param name="user"/><param name="password"/>
    /// <returns/>
    public override Task<bool> CheckPasswordAsync(BackOfficeIdentityUser user, string password)
    {
        //Your implementation

        var result = base.CheckPasswordAsync(user, password).Result;

        return Task.FromResult(result);
    }
}

2º - Then in your owin startup, you can use this block of code for your ConfigureUserManagerForUmbracoBackOffice:

var appCtx = ApplicationContext;
        app.ConfigureUserManagerForUmbracoBackOffice<BackOfficeUserManager, BackOfficeIdentityUser>(
            appCtx,
            (options, context) =>
            {
                var membershipProvider = MembershipProviderExtensions.GetUsersMembershipProvider().AsUmbracoMembershipProvider();
                var store = new BackOfficeUserStore(
                    appCtx.Services.UserService,
                    appCtx.Services.ExternalLoginService,
                    membershipProvider);
                return new CustomBackOfficeUserManager(store, options, membershipProvider);
            });

This solution ill keep using the umbraco UserStore and the base methods of UserManager.
