  Hi,

  The middleware is just an example, you need to change the code according to your needs.

  

  For your case, you need to replace the AbpClaimTypes.Role claim.

  Try

  public static class RefreshRolesMiddlewareExtension
  {
      public static IApplicationBuilder UseRefreshRolesMiddleware(this IApplicationBuilder app)
      {
          return app.Use(async (ctx, next) =>
          {
              var currentUser = ctx.RequestServices.GetRequiredService<ICurrentUser>();
  
              if (!currentUser.IsAuthenticated)
              {
                  await next();
                  return;
              }
  
              var userManager = ctx.RequestServices.GetRequiredService<IdentityUserManager>();
  
              var currentPrincipalAccessor = ctx.RequestServices.GetRequiredService<ICurrentPrincipalAccessor>();
              var user = await userManager.GetByIdAsync(currentUser.GetId());
              var roles= await userManager.GetRolesAsync(user);
              var claims = currentPrincipalAccessor.Principal.Claims.ToList();
  
              claims.RemoveAll(x => x.Type == AbpClaimTypes.Role);
              claims.AddRange(roles.Select(x=> new Claim(AbpClaimTypes.Role, x)));
  
              using (currentPrincipalAccessor.Change(claims))
              {
                  await next();
              }

  Hi,

  Please try:

  public static class RefreshRolesMiddlewareExtension

      public static IApplicationBuilder UseRefreshRolesMiddleware(this IApplicationBuilder app)
      {
          return app.Use(async (ctx, next) =>
          {
              var currentUser = ctx.RequestServices.GetRequiredService<ICurrentUser>();
  
              if (!currentUser.IsAuthenticated)

              var userManager = ctx.RequestServices.GetRequiredService<IdentityUserManager>();
  
              var currentPrincipalAccessor = ctx.RequestServices.GetRequiredService<ICurrentPrincipalAccessor>();
              var user = await userManager.GetByIdAsync(currentUser.GetId());
              var roles= await userManager.GetRolesAsync(user);
  
              currentPrincipalAccessor.Principal.Identities.First().AddClaims(roles.Select(x=> new Claim(AbpClaimTypes.Role, x)));
  
              await next();
  
          });
      }
