  You are experiencing severe performance issues during login when users are mapped to a large number of organization units (e.g., 1500+ per user, 3000 users total) after upgrading to ABP 9.0. This is a known challenge when the claims principal is populated with a very large number of organization unit claims, as each claim is loaded and processed during authentication.

  Solution & Recommendations

  1. Claims Optimization:

     • By default, ABP adds all organization unit IDs as claims to the user during login. With thousands of claims, this can cause significant performance degradation.
     • You should avoid loading all organization unit claims into the user's principal if not strictly necessary for every request.

  2. Recommended Approaches:

     • Reduce Claims Count: Only add essential claims to the principal. If you only need to check organization membership occasionally, consider querying the database or using a cache instead of claims.
     • Custom Claims Principal Factory: Override the IUserClaimsPrincipalFactory to limit or filter the organization unit claims added to the principal.
     • Use Data Filters: For data access, use ABP's data filtering and permission system instead of relying on claims for every organization unit.
     • Paging or Caching: If you must check many organization units, implement paging or caching strategies outside the claims system.

  3. Reference Implementation:

     • See the official documentation for organization units and claims:
       • ABP Identity Module: Organization Units
     • See a similar performance issue and solution discussion:
       • ABP Support: Register + Login slow with many tenants/claims
       • ABP Support: Identity Server running slow

  4. Example: Custom Claims Principal Factory

  public class MyUserClaimsPrincipalFactory : AbpUserClaimsPrincipalFactory
     {
         public MyUserClaimsPrincipalFactory(
             UserManager<IdentityUser> userManager,
             RoleManager<IdentityRole> roleManager,
             IOptions<IdentityOptions> optionsAccessor)
             : base(userManager, roleManager, optionsAccessor)
         {
         }
  
         protected override async Task AddOrganizationUnitsAsync(IdentityUser user, ClaimsIdentity identity)
         {
             // Only add a limited number of OUs, or none, or a summary claim
             // Example: Add only the first 10 OUs
             var organizationUnits = await UserManager.GetOrganizationUnitsAsync(user);
             foreach (var ou in organizationUnits.Take(10))
             {
                 identity.AddClaim(new Claim(AbpOrganizationUnitClaimType, ou.Id.ToString()));
             }
         }
     }
  

  • Register your custom factory in DI.

  5. ABP 9.x Changes:
     • ABP 9 introduced some changes in claims and dynamic claims handling. If you have custom logic, review the upgrade notes and ensure your customizations are compatible.

  Summary

  • Do not add thousands of claims to the user principal.
  • Use custom claims principal logic to limit claims.
  • Use ABP's data filtering and permission system for organization unit checks.
  • Review and optimize your login and claims logic for large-scale organization unit scenarios.
