  1. Solution

  • Root cause: You are issuing too many claims into the authentication ticket (cookie). In ABP/ASP.NET Core Identity, role claims are added by the claims principal factory. You can fully control which role claims are emitted and reduce cookie size by customizing ABP’s claims principal pipeline.

  • Recommended approach: Implement an IAbpClaimsPrincipalContributor that only adds the roles for the current user (and optionally, compresses or limits them) and removes any global/bulk role claims. Register it in your HttpApi.Host/AuthServer.

  Example: Only include roles assigned to the current user and limit count

  using System.Linq;
  using System.Security.Claims;
  using System.Threading.Tasks;
  using Microsoft.Extensions.DependencyInjection;
  using Volo.Abp.DependencyInjection;
  using Volo.Abp.Security.Claims;
  using Volo.Abp.Users;
  using Volo.Abp.Identity;
  using Volo.Abp;
  
  public class MinimalRolesClaimsContributor : IAbpClaimsPrincipalContributor, ITransientDependency
  {
      // Adjust as needed
      private const int MaxRolesToInclude = 20;
  
      public async Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
      {
          var identity = context.ClaimsPrincipal.Identities.FirstOrDefault();
          if (identity == null)
          {
              return;
          }
  
          // 1) Remove any pre-added Role claims to avoid duplication or global roles
          var existingRoleClaims = identity.FindAll(AbpClaimTypes.Role).ToList();
          foreach (var c in existingRoleClaims)
          {
              identity.TryRemoveClaim(c);
          }
  
          // 2) Add only current user's roles (optionally limit the count)
          var userId = identity.FindUserId();
          if (!userId.HasValue)
          {
              return;
          }
  
          var userRoleFinder = context.ServiceProvider.GetRequiredService<IIdentityUserRoleFinder>();
          var roleRepository = context.ServiceProvider.GetRequiredService<IIdentityRoleRepository>();
  
          // Get role IDs for the user
          var roleIds = await userRoleFinder.GetRoleIdsAsync(userId.Value);
  
          // Load roles and order deterministically
          var roles = await roleRepository.GetListAsync(roleIds);
          var roleNames = roles
              .Select(r => r.Name)
              .OrderBy(n => n)
              .Take(MaxRolesToInclude)
              .ToList();
  
          foreach (var roleName in roleNames)
          {
              identity.AddClaim(new Claim(AbpClaimTypes.Role, roleName));
          }
  
          // Optional: If you want to avoid multiple Role claims, you can add a single compact claim:
          // identity.AddClaim(new Claim("roles_csv", string.Join(",", roleNames)));
          // Then, customize your authorization policy provider to read from this single claim instead of multiple Role claims.
      }
  }
  

  • Register the contributor in your module (e.g., in your HttpApi.Host/AuthServer module):

  using Microsoft.Extensions.DependencyInjection;
  using Volo.Abp.Modularity;
  using Volo.Abp.Security.Claims;
  
  [DependsOn(typeof(AbpIdentityHttpApiModule))] // or your relevant modules
  public class YourHostModule : AbpModule
  {
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          Configure<AbpClaimsPrincipalFactoryOptions>(options =>
          {
              // Add our contributor at the end (or earlier if you want to override earlier contributors)
              options.Contributors.Add<MinimalRolesClaimsContributor>();
          });
      }
  }
  

  • Additional tactics to reduce header/cookie size:
    • If you’re using cookie auth, prefer sliding expiration and keep claims minimal. Move large, infrequently used data out of the cookie and load on demand from DB.
    • If using OpenIddict/IdentityServer, keep id_token small; put roles only in access_token when necessary and for APIs. For SPA/React, you don’t need to send all roles in cookies if you can authorize on the server using permissions.
    • Prefer permission checks (ABP’s permission system) instead of flooding the cookie with thousands of Role claims. Permissions are evaluated server-side and cached.
    • If you must keep all permissions/roles, consider JWT access tokens for the SPA and keep the cookie (for server) lean, or store roles compactly (e.g., single CSV claim or hashed/bitset mapping) and adapt your authorization policy provider.

  2. Sources

  • ABP Authorization – Claims Principal Factory (extending claims via IAbpClaimsPrincipalContributor)
    • No verified source available for this specific query. This approach aligns with common ABP conventions, but specific official documentation for this exact scenario is not available.

  also, we want to keep abpidentity roles by default as it is required to get permission, roles etc.

  1. Solution

  • Keep ABP Identity’s default behavior, but stop emitting all roles for every user. ABP doesn’t need role claims in the cookie to authorize permissions; it evaluates permissions server-side. So, minimize role claims while preserving Identity/permission functionality.

  • Option A (recommended): Do not add any role claims at sign-in; rely on ABP permission system

    • Implement an IAbpClaimsPrincipalContributor that removes role claims from the cookie while leaving everything else intact. ABP Identity and permission checks still work, since permission evaluation queries stores/caches, not the cookie’s entire role list.

  using System.Linq;
    using System.Security.Claims;
    using System.Threading.Tasks;
    using Microsoft.Extensions.DependencyInjection;
    using Volo.Abp.DependencyInjection;
    using Volo.Abp.Security.Claims;
  
    public class RemoveBulkRoleClaimsContributor : IAbpClaimsPrincipalContributor, ITransientDependency
    {
        public Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
        {
            var identity = context.ClaimsPrincipal.Identities.FirstOrDefault();
            if (identity == null) return Task.CompletedTask;
  
            // Remove pre-added role claims to reduce cookie size
            var roleClaims = identity.FindAll(AbpClaimTypes.Role).ToList();
            foreach (var c in roleClaims)
            {
                identity.TryRemoveClaim(c);
            }
  
            // Optionally add only a marker claim (tiny) if your app needs to know user has roles
            // identity.AddClaim(new Claim("has_roles", "true"));
  
            return Task.CompletedTask;
        }
    }
  

  • Register the contributor in your AuthServer/HttpApi.Host module:

  using Volo.Abp.Modularity;
    using Volo.Abp.Security.Claims;
  
    public class YourAuthServerModule : AbpModule
    {
        public override void ConfigureServices(ServiceConfigurationContext context)
        {
            Configure<AbpClaimsPrincipalFactoryOptions>(options =>
            {
                options.Contributors.Add<RemoveBulkRoleClaimsContributor>();
            });
        }
    }
  

  • Option B (if you must keep role claims, include only roles assigned to the current user)
    • Replace “all roles” with “user’s roles only,” which keeps ABP Identity roles intact but dramatically reduces the count:

  using System.Linq;
    using System.Security.Claims;
    using System.Threading.Tasks;
    using Microsoft.Extensions.DependencyInjection;
    using Volo.Abp.DependencyInjection;
    using Volo.Abp.Identity;
    using Volo.Abp.Security.Claims;
    using Volo.Abp.Users;
  
    public class UserOnlyRolesClaimsContributor : IAbpClaimsPrincipalContributor, ITransientDependency
    {
        public async Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
        {
            var identity = context.ClaimsPrincipal.Identities.FirstOrDefault();
            if (identity == null) return;
  
            // Remove any pre-added Role claims first
            var existingRoleClaims = identity.FindAll(AbpClaimTypes.Role).ToList();
            foreach (var c in existingRoleClaims)
            {
                identity.TryRemoveClaim(c);
            }
  
            var userId = identity.FindUserId();
            if (!userId.HasValue) return;
  
            var userRoleFinder = context.ServiceProvider.GetRequiredService<IIdentityUserRoleFinder>();
            var roleRepository = context.ServiceProvider.GetRequiredService<IIdentityRoleRepository>();
  
            var roleIds = await userRoleFinder.GetRoleIdsAsync(userId.Value);
            if (!roleIds.Any()) return;
  
            var roles = await roleRepository.GetListAsync(roleIds);
            foreach (var role in roles)
            {
                identity.AddClaim(new Claim(AbpClaimTypes.Role, role.Name));
            }
        }
    }
  

  • Register similarly via AbpClaimsPrincipalFactoryOptions.

  • Option C (compact roles into a single small claim)

    • If you need roles in the client but must keep the cookie tiny, replace multiple role claims with one compact claim (e.g., CSV or short IDs) and read it in your UI. Note: ASP.NET Core’s built-in [Authorize(Roles="...")] expects standard role claims, so if you compact them, you’ll need a custom IAuthorizationPolicyProvider/ClaimsTransformation to interpret it.

  • If you use OpenIddict/JWT for SPA:

    • Put roles only in the access_token (API use) and keep id_token/cookie minimal. You can control token claims via OpenIddict server events (e.g., ProcessSignInContext) to avoid bloating cookies while still letting APIs receive roles.

  • General tips to avoid “request header too long”:

    • Prefer permission checks over role claims in cookies.
    • Avoid adding per-permission claims; check permissions server-side.
    • Reduce or eliminate large custom claims in the cookie.
