Yes — injecting an inline <style> via ABP’s layout hook mechanism is an officially supported customization approach for MVC/Razor Pages, and it’s the correct way to generate path-base-aware URLs (because it runs in Razor with Url.Content("~/...") / IUrlHelper and therefore respects PathBase).
Concrete approach (works with LeptonX 5.2.x bundling paths):
@* /Pages/Shared/Components/LpxCssVariables/Default.cshtml (or any partial you include via a hook) *@
<style>
:root {
--lpx-theme-light-bg: url('@Url.Content("~/LeptonX/images/login-pages/login-bg-img-light.svg")');
--lpx-theme-dim-bg: url('@Url.Content("~/LeptonX/images/login-pages/login-bg-img-dim.svg")');
--lpx-theme-dark-bg: url('@Url.Content("~/LeptonX/images/login-pages/login-bg-img-dark.svg")');
--lpx-logo: url('@Url.Content("~/images/logo/leptonx/icon.svg")');
--lpx-logo-icon: url('@Url.Content("~/images/logo/leptonx/icon.svg")');
}
</style>
Why this is the “missing mechanism”:
/Themes/LeptonX/.../css/bootstrap-dark.css, so relative url(...) inside static CSS becomes relative to that deep path (as you observed)./images/... ignores UsePathBase.Url.Content("~/images/...") produces /server/images/... when PathBase=/server, so it works in all hosting modes.Alternative supported mechanism (also server-side): you can also add a dedicated CSS file as a bundle contributor, but that still won’t solve PathBase unless the file content is generated server-side. For this specific problem, layout hook + inline style is the correct pattern.

Fix (recommended): stop using root-absolute URLs in global-styles.css and switch to “application-root relative” URLs.
In a static CSS file, paths starting with / will always resolve from the host root (ignoring UsePathBase). To make the browser automatically include the path base (e.g. /server), change them to relative paths (no leading /).
Example (HttpApi.Host/wwwroot/global-styles.css):
:root {
/* was: url('/LeptonX/images/...') */
--lpx-theme-light-bg: url('LeptonX/images/login-pages/login-bg-img-light.svg');
--lpx-theme-dim-bg: url('LeptonX/images/login-pages/login-bg-img-dim.svg');
--lpx-theme-dark-bg: url('LeptonX/images/login-pages/login-bg-img-dark.svg');
}
:root {
/* was: url('/images/...') */
--lpx-logo: url('images/logo/leptonx/icon.svg');
--lpx-logo-icon: url('images/logo/leptonx/icon.svg');
}
With this change, when the CSS file is served from https://example.com/server/global-styles.css, the browser resolves:
url('images/logo/leptonx/icon.svg') → https://example.com/server/images/logo/leptonx/icon.svg (works under a path base)
If you prefer not to edit the generated file: move these CSS variable overrides into a custom global CSS file you control (still under wwwroot) and add it to the global bundle after theme styles, then use the same “no leading /” relative URLs there. ABP supports adding a global CSS file to the global style bundle via bundling options (MVC/Razor Pages).
(This is the official customization mechanism; the key is: don’t use /... in static CSS when hosting under a sub-path.)

Yes. In ABP, ICurrentUser is populated from the current ClaimsPrincipal (typically HttpContext.User in an HTTP request). So the correct way is to implement your sessionCode validation as a real ASP.NET Core authentication scheme that creates a ClaimsPrincipal when the header is valid. Once you do that, ABP will automatically see the authenticated principal and ICurrentUser will work in application/domain services, auditing, authorization, etc.
Implement a custom authentication handler reading your header (example: X-Session-Code), call System B to validate it and fetch user info, then create claims ABP understands (at minimum: AbpClaimTypes.UserId, optionally username, roles, tenant, etc.).
using System.Security.Claims;
using System.Text.Encodings.Web;
using Microsoft.AspNetCore.Authentication;
using Microsoft.Extensions.Options;
using Volo.Abp.Security.Claims;
public sealed class SessionCodeAuthHandler
: AuthenticationHandler<AuthenticationSchemeOptions>
{
public const string SchemeName = "SessionCode";
public SessionCodeAuthHandler(
IOptionsMonitor<AuthenticationSchemeOptions> options,
ILoggerFactory logger,
UrlEncoder encoder)
: base(options, logger, encoder)
{
}
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
if (!Request.Headers.TryGetValue("X-Session-Code", out var values))
{
return AuthenticateResult.NoResult();
}
var sessionCode = values.ToString();
if (string.IsNullOrWhiteSpace(sessionCode))
{
return AuthenticateResult.NoResult();
}
// 1) Validate against System B and get user info
// (Pseudo-code; replace with your actual HTTP call / SDK)
var externalUser = await ValidateWithSystemBAsync(sessionCode);
if (externalUser is null)
{
return AuthenticateResult.Fail("Invalid sessionCode");
}
// 2) Build ClaimsPrincipal so ABP's ICurrentUser can read it
var claims = new List<Claim>
{
new(AbpClaimTypes.UserId, externalUser.UserId.ToString()),
new(AbpClaimTypes.UserName, externalUser.UserName ?? externalUser.UserId.ToString()),
};
// Optional: tenant
// claims.Add(new Claim(AbpClaimTypes.TenantId, externalUser.TenantId.ToString()));
// Optional: roles
// foreach (var role in externalUser.Roles) claims.Add(new Claim(AbpClaimTypes.Role, role));
var identity = new ClaimsIdentity(claims, Scheme.Name);
var principal = new ClaimsPrincipal(identity);
var ticket = new AuthenticationTicket(principal, Scheme.Name);
return AuthenticateResult.Success(ticket);
}
private Task<dynamic?> ValidateWithSystemBAsync(string sessionCode)
{
// Implement: call System B, return null if invalid, otherwise user payload.
throw new NotImplementedException();
}
}

}
Ensure the ASP.NET Core authentication/authorization middleware runs (ABP templates already do). After that:
[Authorize].ICurrentUser.Id, ICurrentUser.UserName, ICurrentUser.Roles, etc. will be populated based on the claims you created.Alternative (only for special cases like background jobs / manual flows): you can set the principal explicitly for a scope using ICurrentPrincipalAccessor.Change(newPrincipal), but for HTTP requests the proper/clean approach is the custom authentication scheme described above, so everything (authorization, auditing, ICurrentUser) is consistent.

UNABLE_TO_VERIFY_LEAF_SIGNATURE is not an ABP/OpenIddict authentication failure. It’s a Node.js TLS trust-chain validation error during SSR when Node calls your ABP backend over HTTPS and cannot validate the server certificate chain (very common with missing intermediate certs, corporate TLS interception, or self-signed/internal CA certs).
That’s why it can “work in browser/Postman” (they often use OS trust store / may have different trust behavior) but fail in SSR (Node uses its own CA bundle).
Fix it on the certificate / chain side (recommended):
fullchain.pem on Let’s Encrypt setups).Fix it on the SSR Node runtime side (when you must trust a private CA):
corp-root-ca.pem.NODE_EXTRA_CA_CERTS=/path/to/corp-root-ca.pemNODE_DEBUG=tls
This makes Node trust that CA and resolves UNABLE_TO_VERIFY_LEAF_SIGNATURE without disabling TLS checks.Avoid this “quick fix” in production (insecure):
NODE_TLS_REJECT_UNAUTHORIZED=0 or using an HTTPS agent with rejectUnauthorized: false will bypass TLS verification entirely. It may “make it work”, but it weakens security and should not be used beyond local debugging.After TLS is fixed, if the API is actually secured and SSR must call it authenticated:

ICurrentTenant.Id). If tenant resolution fails, CurrentTenant.Id becomes null and the user is created under Host."tenantId": null, which means the Identity endpoint is running in Host context in production (even though you are in a tenant UI).Apply the following production fixes (these are the common causes where local works but production doesn’t):
UseMultiTenancy() order is correct in the HTTP pipeline/api/identity/users is served), the middleware order must include Multi-Tenancy in the right place. Use this order:app.UseRouting();
app.UseAuthentication();
app.UseMultiTenancy(); // must be AFTER UseAuthentication
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
If UseMultiTenancy() runs before authentication, tenant-related claims/header/cookie context may not be applied as expected in some deployments.
__tenant header. Some NGINX setups drop headers with underscores by default. Add:underscores_in_headers on;
and reload NGINX. Otherwise, the backend won’t receive __tenant, tenant resolution fails, and Identity endpoints operate as Host.

To limit a user to only their own folder, you should not rely on “normal” (RBAC) permissions alone (like FileManagement.Directories, FileManagement.Files, etc.). Those permissions apply to all directories/files.
Instead, use Resource-Based Authorization in ABP and treat each directory (folder) as a resource instance.
In your PermissionDefinitionProvider, define:
public class MyPermissionDefinitionProvider : PermissionDefinitionProvider
{
public override void Define(IPermissionDefinitionContext context)
{
var group = context.AddGroup("MyApp");
var fileGroup = group.AddPermission("MyApp.FileManagement");
fileGroup.AddChild("MyApp.FileManagement.ManageDirectoryPermissions");
context.AddResourcePermission(
name: "MyApp.FileManagement.Directory.View",
resourceName: "MyApp.FileManagement.Directory",
managementPermissionName: "MyApp.FileManagement.ManageDirectoryPermissions"
);
context.AddResourcePermission(
name: "MyApp.FileManagement.Directory.Write",
resourceName: "MyApp.FileManagement.Directory",
managementPermissionName: "MyApp.FileManagement.ManageDirectoryPermissions"
);
}
}
Whenever you return directory content or allow upload/download/move/delete, check the permission against the directory instance (resource key = directory id).
public class MyDirectoryAppService : ApplicationService
{
public async Task<DirectoryContentDto> GetContentAsync(Guid directoryId)
{
// Throws if user is not granted for this specific directory
await AuthorizationService.CheckAsync(
resource: directoryId.ToString(),
policyName: "MyApp.FileManagement.Directory.View"
);
// Then call File Management services/repositories as needed...
// return await _directoryDescriptorAppService.GetContentAsync(...);
}
}
In ABP, the point is: check permission using (resourceName + resourceKey), not just [Authorize("Some.Permission")].
When you create the user’s root directory (e.g., user-{CurrentUser.Id}), grant resource permissions to that same user programmatically:
Directory.View and Directory.Write to provider U (user) with providerKey = the userId,(How you store and manage these grants is handled by ABP’s resource permission infrastructure; your job is to define the resource permissions and enforce them.)
If you want admins to open a “Permissions” dialog for a specific folder and share it with other users/roles, ABP provides a ready modal for resource permission management (same concept as the docs example). This is the cleanest way to manage “folder sharing” without writing your own UI.

var userId = CurrentUser.GetId();
var userRootName = $"user-{userId}";

Chat history / “New chat” behavior (ABP Studio 2.2.6): In ABP Studio’s AI Assistant, starting a New chat is expected to start a fresh thread. If the previous thread is not being retained/visible after you switch, that’s an AI Assistant chat persistence/UI behavior (not a token optimization feature). There’s no ABP-side setting I can point to (verified) that forces Studio to keep multiple chats side-by-side or to merge history across chats in 2.2.6.
Token consumption concern: Because each new chat starts without prior context, you’ll naturally re-send background, which consumes more tokens. There is no verified, documented way in ABP Studio 2.2.6 to “reuse” earlier chats automatically to avoid that.
“AI assistant can’t check the open solution” limitation: In 2.2.6, the AI Assistant not being able to automatically inspect your currently opened solution/code is consistent with a product limitation; I don’t have a verified source indicating that ABP Studio 2.2.6 can index your open solution and answer by reading it directly.
Practical next step (official channel): Since these items are ABP Studio product/feature requests/behavior (chat persistence, cross-chat memory, solution-aware code reading) rather than something you can fix in your ABP app code, please report it to the ABP team via the contact channel:
Related (verified) note: ABP Studio release notes mention “Fixed AI Assistant chat problems” in a later release stream, so upgrading ABP Studio to a newer version than 2.2.6 may help if what you’re hitting is a known AI Assistant bug (but the note doesn’t specifically confirm your exact two issues):

This is a known incompatibility in the ABP 10.2 line: ABP removed the third‑party jquery-form integration (so $.fn.ajaxSubmit / $.fn.ajaxForm are no longer available), but CmsKit Pro Admin (10.2.0) still contains scripts calling ajaxSubmit(), which results in TypeError: n.ajaxSubmit is not a function.
Definitive fix: upgrade to a CmsKit Pro package version where those scripts were updated to use ABP’s current abpAjaxForm implementation (i.e., not ajaxSubmit). Since I can’t access/verify the commercial package changelog via the available tools here, I can’t name the exact fixed patch version.
Immediate workaround (no waiting for a package update): add jquery-form back into the global bundles so ajaxSubmit() exists again:
@abp/jquery-form is present in your web theme/package (you already have it, as you stated the file exists under wwwroot/libs/jquery-form/jquery.form.min.js).using Volo.Abp.AspNetCore.Mvc.UI.Bundling;
using Volo.Abp.Modularity;
[DependsOn(typeof(AbpAspNetCoreMvcUiBundlingModule))]
public class YourWebModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure<AbpBundlingOptions>(options =>
{
// Add to the global script bundle (adjust bundle name if your UI uses a different one)
options.ScriptBundles.Configure(
StandardBundles.Scripts.Global,
bundle =>
{
bundle.AddFiles("/libs/jquery-form/jquery.form.min.js");
});
});
}
}
ajaxSubmit() to abpAjaxForm() / native FormData + $.ajax approach. However, since those files come from the NuGet/package, the practical way is to override/replace the embedded resource in your app (virtual file system) or serve your own patched scripts. (This is more invasive than just re-bundling jquery.form.min.js.)Sources (validated)
