2. Click SAML.
3. In the Basic SAML section, add the links to your Knocknoc instance.
   1. Set the Indentifier (Entity ID) to https://demo.knoc.cloud/api/saml/metadata

      3. Set Source Attribute to the default login duration in seconds for users logging in to Knocknoc. You can manually override this with a user attribute later for specific users.
         
   6. Add a third New Claim
      1. Set the Name as "username"
      2. Leave Source as Attribute.
      3. Set Source Attribute "user.userprincipalname"
         
         
         
5. Go to SAML Certificates section
   
   1. Generate a new certificate and key, this can be done on a Linux host using the below command.
      openssl req -new -x509 -days 3650 -nodes -subj /CN=Knocknoc/ -out user-demo-knoc-cloud.crt -keyout user-demo-knoc-cloud.key
      
   2. Convert the certificate to pfx using the following command.
      openssl pkcs12 -export -out user-demo-knoc-cloud.pfx -inkey user-demo-knoc-cloud.key -in user-demo-knoc-cloud.crt
   3. Enter a password and note it down.
   4. Import Certificate, select the pfx certificate you just created and enter the password.

   1. Copy the Login URL, this will be required for the Knocknoc SAML config.

Knocknoc SAML Config

1. Login In the Knocknoc admin interface.
2. Click on Settings on the left.
   
3. Under Public URL enter you knocknoc url. Note: do not add a / at the end of the URL.
4. For the SAMLMetaDataFile, upload the xml file you downloaded from EntraID.
5. For the SAMLCertFile, upload the certificate (.crt) file you created in during the SAML Configuration.
6. For the SAMLKeyFile, upload the key (.key) file you created in during the SAML Configuration.
7. For the SAMLMetadataUrl, paste the Login URL copied in Step 6 of the previous section.
   
8. Click Save.

Final Testing

Assuming you granted your own user permission to one or more Knocknoc groups in EntraID, you should now be able to login to Knocknoc using SSO.

1. Browse to https://demo.knoc.cloud
2. There should now be an "SSO Login" button.
3. Click this, if you are not already authenticated to your IdP you should now be directed to the IdP login page. Note: If you are already authenticated you'll simply be redirected to an authenticated Knocknoc session.
4. If ACLs have already been added you should also see these now say Granted.

If this all works, congratulations! You've successfully run the SAML gauntlet.
