Checklist to resolve the login button issue:
Check AuthServer is Running:
Correct Redirect URLs:
appsettings.json (AuthServer and Angular), make sure the App:SelfUrl and AuthServer:Authority are set to the correct URLs (e.g., http://localhost:4200 for Angular, and the actual AuthServer URL).environment.ts should have oAuthConfig.issuer set to the AuthServer URL.CORS Configuration:
appsettings.json of AuthServer, add the Angular URL to CorsOrigins:"App": {
"CorsOrigins": "http://localhost:4200"
}
Hosts File (if using custom domains):
angular.localtest.me), ensure your hosts file and all URLs match.Browser Console Errors:
Rebuild and Restart:
abp install-libs, rebuild, and restart all backend and frontend projects.Check OAuth Configuration in Angular:
environment.ts:oAuthConfig: {
issuer: 'https://localhost:44368', // AuthServer URL
clientId: 'AbpSolution3_App', // Should match your app registration
scope: 'offline_access openid profile role email phone'

When creating a new tenant via the ABP Tenant Management API, the admin user for the tenant should be assigned the default roles and permissions as part of the tenant seeding process. However, if the admin user cannot create additional users (receiving a 403 Forbidden error), it usually means the necessary permissions (such as "Identity.Users.Create") are not granted to the admin role or the admin user.
This issue can occur if:
Check Permission Seeding Logic
DbMigrationService or similar) assigns all required permissions to the admin role for each tenant.Example logic:
foreach (var tenant in tenants)
{
using (_currentTenant.Change(tenant.Id))
{
await SeedDataAsync(tenant);
}
}
Verify Permission Assignment
AbpIdentity.Users.Create).AbpPermissionGrants table) or via the Permission Management UI.Update Seeding if Needed
Test Tenant Creation
Reference Example
await _permissionManager.SetForRoleAsync(
roleId: adminRoleId,
permissionName: "AbpIdentity.Users.Create",
isGranted: true
);
This ensures the admin role has the required permission.

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.

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
});

其他
请根据上述建议调整 Nginx 配置和 ABP 后端设置，问题即可解决。
