* Add single sign-on support via SSPI on Windows * Ensure plugins implement interface * Ensure plugins implement interface * Move functions used only by the SSPI auth method to sspi_windows.go * Field SSPISeparatorReplacement of AuthenticationForm should not be required via binding, as binding will insist the field is non-empty even if another login type is selected * Fix breaking of oauth authentication on download links. Do not create new session with SSPI authentication on download links. * Update documentation for the new 'SPNEGO with SSPI' login source * Mention in documentation that ROOT_URL should contain the FQDN of the server * Make sure that Contexter is not checking for active login sources when the ORM engine is not initialized (eg. when installing) * Always initialize and free SSO methods, even if they are not enabled, as a method can be activated while the app is running (from Authentication sources) * Add option in SSPIConfig for removing of domains from logon names * Update helper text for StripDomainNames option * Make sure handleSignIn() is called after a new user object is created by SSPI auth method * Remove default value from text of form field helper Co-Authored-By: Lauris BH <lauris@nix.lv> * Remove default value from text of form field helper Co-Authored-By: Lauris BH <lauris@nix.lv> * Remove default value from text of form field helper Co-Authored-By: Lauris BH <lauris@nix.lv> * Only make a query to the DB to check if SSPI is enabled on handlers that need that information for templates * Remove code duplication * Log errors in ActiveLoginSources Co-Authored-By: Lauris BH <lauris@nix.lv> * Revert suffix of randomly generated E-mails for Reverse proxy authentication Co-Authored-By: Lauris BH <lauris@nix.lv> * Revert unneeded white-space change in template Co-Authored-By: Lauris BH <lauris@nix.lv> * Add copyright comments at the top of new files * Use loopback name for randomly generated emails * Add locale tag for the SSPISeparatorReplacement field with proper casing * Revert casing of SSPISeparatorReplacement field in locale file, moving it up, next to other form fields * Update docs/content/doc/features/authentication.en-us.md Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> * Remove Priority() method and define the order in which SSO auth methods should be executed in one place * Log authenticated username only if it's not empty * Rephrase helper text for automatic creation of users * Return error if more than one active SSPI auth source is found * Change newUser() function to return error, letting caller log/handle the error * Move isPublicResource, isPublicPage and handleSignIn functions outside SSPI auth method to allow other SSO methods to reuse them if needed * Refactor initialization of the list containing SSO auth methods * Validate SSPI settings on POST * Change SSPI to only perform authentication on its own login page, API paths and download links. Leave Toggle middleware to redirect non authenticated users to login page * Make 'Default language' in SSPI config empty, unless changed by admin * Show error if admin tries to add a second authentication source of type SSPI * Simplify declaration of global variable * Rebuild gitgraph.js on Linux * Make sure config values containing only whitespace are not accepted

`websspi` will be an HTTP middleware for Golang that uses Kerberos for single sign-on (SSO) authentication of browser based clients in a Windows environment.
|
|
|
|
The main goal is to create a middleware that performs authentication of HTTP requests without the need to create or use keytab files.
|
|
|
|
The middleware will implement the scheme defined by RFC4559 (SPNEGO-based HTTP Authentication in Microsoft Windows) to exchange security tokens via HTTP headers and will use SSPI (Security Support Provider Interface) to authenticate HTTP requests.
|
|
|
|
## How to use
|
|
|
|
The examples directory contains a simple web server that demonstrates how to use the package.
|
|
Before trying it, you need to prepare your environment:
|
|
|
|
1. Create a separate user account in active directory, under which the web server process will be running (eg. `user` under the `domain.local` domain)
|
|
|
|
2. Create a service principal name for the host with class HTTP:
|
|
- Start Command prompt or PowerShell as domain administrator
|
|
- Run the command below, replacing `host.domain.local` with the fully qualified domain name of the server where the web application will be running, and `domain\user` with the name of the account created in step 1.:
|
|
|
|
setspn -A HTTP/host.domain.local domain\user
|
|
|
|
3. Start the web server app under the account created in step 1.
|
|
|
|
4. If you are using Chrome, Edge or Internet Explorer, add the URL of the web app to the Local intranet sites (`Internet Options -> Security -> Local intranet -> Sites`)
|
|
|
|
5. Start Chrome, Edge or Internet Explorer and navigate to the URL of the web app (eg. `http://host.domain.local:9000`)
|
|
|
|
6. The web app should greet you with the name of your AD account without asking you to login. In case it doesn't, make sure that:
|
|
|
|
- You are not running the web browser on the same server where the web app is running. You should be running the web browser on a domain joined computer (client) that is different from the server
|
|
- There is only one HTTP/... SPN for the host
|
|
- The SPN contains only the hostname, without the port
|
|
- You have added the URL of the web app to the `Local intranet` zone
|
|
- The clocks of the server and client should not differ with more than 5 minutes
|
|
- `Integrated Windows Authentication` should be enabled in Internet Explorer (under `Advanced settings`)
|
|
|
|
## Security requirements
|
|
|
|
- SPNEGO HTTP provides no facilities for protecting the HTTP headers or data including the Authorization and WWW-Authenticate headers, which means that the HTTP server **MUST** enforce use of SSL to provide confidentiality to data in these headers!
