* 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 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:
Create a separate user account in active directory, under which the web server process will be running (eg. user under the domain.local domain)
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
Start the web server app under the account created in step 1.
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)
Start Chrome, Edge or Internet Explorer and navigate to the URL of the web app (eg. http://host.domain.local:9000)
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!
