  Hi,

  You can try:

  public class MyAbpClaimsPrincipalContributor : IAbpClaimsPrincipalContributor, ITransientDependency
  {
      public Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
      {
          var claimsIdentity = new ClaimsIdentity();
          claimsIdentity.AddIfNotContains(new Claim("ConCurrentUserId", "value"));
          context.ClaimsPrincipal.AddIdentity(claimsIdentity);
  
          return Task.CompletedTask;
      }
  }
  
  public class MyAbpClaimsService : AbpClaimsService
  {
      public MyAbpClaimsService(IProfileService profile, ILogger<DefaultClaimsService> logger) : base(profile, logger)
      {
      }
  
      protected override IEnumerable<string> FilterRequestedClaimTypes(IEnumerable<string> claimTypes)
      {
          return base.FilterRequestedClaimTypes(claimTypes)
              .Union(new []{
                  AbpClaimTypes.TenantId,
                  AbpClaimTypes.EditionId,
                  "ConCurrentUserId"
              });
      }
  }
  
  
  context.Services.Replace(ServiceDescriptor.Transient<IClaimsService, MyAbpClaimsService>());

  @liangshiwei can you please let me know which project I put these Class's in *.application ? . and where does do i put the following line in ... Configure Servcies?

  context.Services.Replace(ServiceDescriptor.Transient<IClaimsService, MyAbpClaimsService>());

  if I am right this just adds the Custom Claim ..... I still have to modify the SignInManager to check if the value of ConCurrentUserId has changed and block login .... am i correct?

  If so which Method in the SignInManager should i use?

  Hi,

  You can put the class these Class to .Web project.

  Add the following code to the ConfigureServices method of .WebModule

  context.Services.Replace(ServiceDescriptor.Transient<IClaimsService, MyAbpClaimsService>());

  How I can get the claim to check the user property ConCurrentUserID, so that I can block login?

  If you are not logged in, you cannot get the user claim, You should query the database values.

  Having a GUID stored as i previously thought will not be a good solution. I am trying to update the security stamp as done in aspnetzero but it doesn't appear towork in abp.io

  public override async Task SignInWithClaimsAsync(Volo.Abp.Identity.IdentityUser user, AuthenticationProperties authenticationProperties, IEnumerable<Claim> additionalClaims)
          {
  
              var userPrincipal = await CreateUserPrincipalAsync(user);
  
              foreach (var claim in additionalClaims)
              {
                  userPrincipal.Identities.First().AddClaim(claim);
              }
  
              await Context.SignInAsync(IdentityConstants.ApplicationScheme,
                  userPrincipal,
                  authenticationProperties ?? new AuthenticationProperties());
  
              await UserManager.UpdateSecurityStampAsync(user);
          }
  

  can you please let me know why the above code doesn't work, when ii test my presios sessions in other browsers are not loged out and invalidated

  Okay The Validate methods are now hitting in my cutom SiginManager but i can't login as a current user seems i get a user is null

  what is the best place to call the below so that i can make all previous sessions in all browsers invalid and just let the current user login?

  if (user != null) { await UserManager.UpdateSecurityStampAsync(user); }

  Hi,

  You can override the CheckPasswordSignInAsync method of SignInManager class

  public override async Task<SignInResult> CheckPasswordSignInAsync(
              IdentityUser user,
              string password,
              bool lockoutOnFailure)
  {
      if (user == null)
      {
          throw new ArgumentNullException(nameof(user));
      }
  
      var error = await PreSignInCheck(user);
      if (error != null)
      {
          return error;
      }
  
      if (await UserManager.CheckPasswordAsync(user, password))
      {
          var alwaysLockout = AppContext
              .TryGetSwitch("Microsoft.AspNetCore.Identity.CheckPasswordSignInAlwaysResetLockoutOnSuccess", out var enabled) && enabled;
          // Only reset the lockout when not in quirks mode if either TFA is not enabled or the client is remembered for TFA.
          if (alwaysLockout || !await IsTfaEnabled(user) || await IsTwoFactorClientRememberedAsync(user))
          {
              await ResetLockout(user);
          }
  
          await UserManager.UpdateSecurityStampAsync(user);
  
          return SignInResult.Success;
      }
      Logger.LogWarning(2, "User failed to provide the correct password.");
  
      if (UserManager.SupportsUserLockout && lockoutOnFailure)
      {
          // If lockout is requested, increment access failed count which might lock out the user
          await UserManager.AccessFailedAsync(user);
          if (await UserManager.IsLockedOutAsync(user))
          {
              return await LockedOut(user);
          }
      }
      return SignInResult.Failed;
  }

  Hi,

  I find the problem, see : https://github.com/abpframework/abp/pull/7814/files

  For now , you need to :

  public class MyAbpSecurityStampValidator : AbpSecurityStampValidator
  {
      protected ITenantConfigurationProvider TenantConfigurationProvider { get; }
      protected ICurrentTenant CurrentTenant { get; }
  
      public MyAbpSecurityStampValidator(
          IOptions<SecurityStampValidatorOptions> options,
          SignInManager<IdentityUser> signInManager,
          ISystemClock systemClock,
          ILoggerFactory loggerFactory,
          ITenantConfigurationProvider tenantConfigurationProvider,
          ICurrentTenant currentTenant) : base(options, signInManager, systemClock, loggerFactory)
      {
          TenantConfigurationProvider = tenantConfigurationProvider;
          CurrentTenant = currentTenant;
      }
  
      [UnitOfWork]
      public override async Task ValidateAsync(CookieValidatePrincipalContext context)
      {
          var tenant = await TenantConfigurationProvider.GetAsync(saveResolveResult: false);
          using (CurrentTenant.Change(tenant?.Id, tenant?.Name))
          {
              await base.ValidateAsync(context);
          }
      }
  }
  
  context.Services.AddScoped<MyAbpSecurityStampValidator>();
  context.Services.AddScoped(typeof(SecurityStampValidator<IdentityUser>), provider => provider.GetService(typeof(MyAbpSecurityStampValidator)));
  context.Services.AddScoped(typeof(ISecurityStampValidator), provider => provider.GetService(typeof(MyAbpSecurityStampValidator)));

  Should i put the following in ConfigureServices or PreConfigureServices in the *WebModule *.web project

  context.Services.AddScoped<MyAbpSecurityStampValidator>();
  context.Services.AddScoped(typeof(SecurityStampValidator<IdentityUser>), provider => provider.GetService(typeof(MyAbpSecurityStampValidator)));
  context.Services.AddScoped(typeof(ISecurityStampValidator), provider => provider.GetService(typeof(MyAbpSecurityStampValidator)));

  I have discoverd a side effect when implementing this in our application to deal with concurrent user.

  It seems when we updated the user via his profile or in the users table under Identity the security stamp is updated and the user is logged out.

  can you please suggest how we can over come this, if the user is updating his profile or via the user table the user shouldn't update its seucirty stamp.

  In our use case the users are not allowed to change their username so i have override the UpdatAsync to be as follows

  (await UserManager.SetUserNameAsync(user, input.UserName)).CheckErrors();

  The above line is what changes the SecurityStamp which forces the user out because we are using AbpSecurityStampValidator to ensure that the same user cant be signed in concurrently using the same username.

      public override async Task<IdentityUserDto> UpdateAsync(Guid id, IdentityUserUpdateDto input)
      {
  
          //ADDED BY VB: To check if all Roles avalible as per license have been consumed.
          if (CurrentUser.UserName != "dfo.admin")
          {
              await CheckCurrentTenantsLicenseConsumed(id, input);
          }
