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.
Claims Optimization:
Recommended Approaches:
IUserClaimsPrincipalFactory to limit or filter the organization unit claims added to the principal.Reference Implementation:
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()));
}
}
}

To resolve the 404 error for email confirmation and password reset links in your multi-tenant ABP microservice solution, you must ensure that:
Your current environment variables show:
App__SelfUrl = https://auth.{0}.cloverleafcms.devAuthServer__Authority = https://authserver.cloverleafcms.devThe AuthServer__Authority should also use the {0} placeholder for tenant resolution:
AuthServer__Authority = https://auth.{0}.cloverleafcms.dev
This allows the system to generate tenant-specific URLs.
App:SelfUrl and AuthServer:Authority settings to generate these links. Both must be tenant-aware.App__SelfUrl and AuthServer__Authority to use the {0} placeholder."App": {
"SelfUrl": "https://auth.{0}.cloverleafcms.dev"
},
"AuthServer": {
"Authority": "https://auth.{0}.cloverleafcms.dev"
}
Follow the official ABP documentation for multi-tenant domain resolving in microservice solutions:
Ensure your configuration matches the documented approach, especially for subdomain-based tenant resolution.
https://auth.cooptrustcu.cloverleafcms.dev/Account/EmailConfirmation?userId=...
Summary:
Update your AuthServer__Authority to use the {0} placeholder for tenant subdomains, ensure your tenant resolver is subdomain-aware, and verify your email link generation uses tenant-specific URLs. Follow the ABP multi-tenant domain resolving guide for full details.

When you define custom permissions in ABP, they must be properly registered and exposed to the permission management system for them to appear in the Identity > Roles > Permissions modal (in Angular or any UI).
If your custom permissions are present in the AbpPermissionGrants table but not visible in the UI, the most common causes are:
Permission Definition Provider Not Registered
Ensure your custom permissions are defined in a class that inherits from PermissionDefinitionProvider and that this provider is registered in your module's configuration. The provider should be in the Application.Contracts project of the module.
Application.Contracts Reference Missing
For modular or microservice solutions, the Application.Contracts project containing your permission definitions must be referenced by the service responsible for permission management (typically the IdentityService or AdministrationService). If this reference is missing, the permissions will not be loaded into the UI.
Rebuild and Restart
After adding new permissions or updating references, rebuild your solution and restart all related services (especially those responsible for permission management).
Cache Issues
ABP caches permission definitions. Clear your distributed cache (e.g., Redis) after making changes to permissions to ensure the UI reflects the latest definitions.
Database Migration
Make sure all migrations are applied and the database is up to date.
Checklist to resolve:
PermissionDefinitionProvider is implemented and registered.References:

The error occurs because the JWT access token payload is Base64Url encoded, and when its length is not a multiple of 4, the atob function in JavaScript throws an error due to missing padding. This is a known issue when decoding JWTs manually.
To fix this in your ABP Angular application, you should add the necessary padding to the token payload before calling atob. Here is the recommended approach:
const tokenBody = accessToken.split('.')[1].replace(/-/g, '+').replace(/_/g, '/');
let paddedTokenBody = tokenBody;
while (paddedTokenBody.length % 4 !== 0) {
paddedTokenBody += '=';
}
const parsedToken = JSON.parse(atob(paddedTokenBody));
Alternatively, you can use a library like jwt-decode to handle the decoding, which automatically manages padding and decoding issues.
This issue and workaround have been discussed in the ABP support portal. The ABP team has acknowledged the problem and suggested similar workarounds until an official fix is released.

The "Unauthorized (401)" error in your Blazor application is likely caused by session or authentication token conflicts when using multiple applications (Admin and Public Website) that share the same authentication server or cookies.
When you log in to the Admin application and then access the Public Website (which may use a different authentication context or tenant), the authentication cookie or token can be overwritten or invalidated. Returning to the Admin app, your session is no longer valid, resulting in a 401 error.
This is a common scenario in ABP-based applications with tiered or separated authentication, especially when both apps are hosted on the same domain or subdomain and share authentication cookies.
Solution Steps:
Use Different Browsers or Incognito Mode:
Configure Cookie Names and Domains:
appsettings.json or authentication configuration, set a unique cookie name for each app:services.ConfigureApplicationCookie(options =>
{
options.Cookie.Name = "YourAppName.Auth";
// Optionally, set options.Cookie.Domain if using subdomains
});
AbpApplicationCookieOptions if using ABP's built-in authentication.Check Token Storage (for JWT):
Review Tenant Context:
Logout and Re-login:
Additional Debugging:
Summary:
This issue is caused by authentication/session conflicts between multiple ABP applications sharing the same authentication server or cookie domain. Isolate sessions by using different browsers/incognito windows, or configure unique cookie names/domains for each app.

你遇到的“样式丢失”问题，通常是因为 ABP 登录页的静态资源（如 CSS、JS、图片等）路径没有被正确代理，导致浏览器无法加载这些资源。ABP 登录页引用的静态资源路径一般是 /libs/、/wwwroot/、/_content/ 等。你需要确保这些路径的代理规则和 /Account/Login 一致，并且代理到正确的后端服务。
你遇到的“登录后跳转 500 错误”，很可能是因为反向代理后端服务时，ABP 应用没有正确获取原始请求的 Host、Scheme 等信息，导致重定向 URL 错误或 Cookie、认证流程异常。ABP 在反向代理环境下需要配置 Forwarded Headers Middleware。
解决方案如下：
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
});

The login page in ABP is provided by the Account Module, and its source code is not included directly in your solution by default. To customize it, you typically create a new PageModel and .cshtml file under Pages/Account in your own project, which overrides the default. The reference implementation for the login page can be found here:
In a multi-tenant setup, the tenant is typically resolved before login using tenant resolvers (domain, query string, or cookie). If you want to derive the tenant automatically (e.g., from username or email), you need to customize the login logic to resolve the tenant before authenticating the user. This is not the default behavior; by default, the user must specify the tenant.
The full source code for open-source ABP modules is available on GitHub:
https://github.com/abpframework/abp/tree/dev/modules
For commercial modules, access is provided to customers with a valid commercial license. You can request access by contacting Volosoft through the official channels after purchasing a commercial license:

The default ABP table design assumes that a user belongs to a single tenant (the AbpUsers table has a TenantId column). This means a user is exclusive to one tenant. If you need users to belong to multiple tenants, you would need to implement a custom solution, as this is not supported out-of-the-box.

To make the sidebar in your ABP Angular application close immediately when you click to minimize it (instead of waiting for the mouse to leave), you need to adjust the sidebar's toggle logic. By default, the sidebar in ABP Angular (especially in the microservice template) uses a hover-based expansion and collapse mechanism, which is why it waits for the mouse to leave before collapsing.
To change this behavior:
Locate the sidebar component, typically found in src/app/layout/sidebar or similar (often named sidebar.component.ts and sidebar.component.html).
Find the method or event handler responsible for toggling the sidebar. This is usually a function like toggleSidebar() or similar, triggered by a button or icon click.
Modify the logic so that clicking the minimize/collapse button immediately sets the sidebar to its collapsed state, regardless of mouse position. For example:
// sidebar.component.ts
isSidebarCollapsed = false;
onToggleSidebar() {
this.isSidebarCollapsed = !this.isSidebarCollapsed;
// Optionally, trigger change detection or emit an event if needed
}
And in your template:
<!-- sidebar.component.html -->
<button (click)="onToggleSidebar()">Toggle Sidebar</button>
<div [class.collapsed]="isSidebarCollapsed">
<!-- Sidebar content -->
</div>
Remove or adjust any mouseleave/mouseenter logic that delays the collapse, so the sidebar responds instantly to the click.
If your sidebar uses a service or state management for its open/close state, ensure the state is updated immediately on click.
This change will make the sidebar collapse as soon as the user clicks the minimize button, providing the immediate feedback you want.
