One of the SAML providers you can use is JumpCloud.

In order to get started with JumpCloud, you will need:

• Jumpcloud account with admin permissions.
• All users are provisioned in Jumpcloud with the same exact email address. We don't create new user accounts with SSO. 
• Administrator level access in Hudu.

Configuring JumpCloud

1. Go to the JumpCloud Admin -> SSO -> +
2. At the bottom of the panel, click Can't Find an Application -> Custom SAML App
3. In General Info, give the app a name and an optional description
4. In the SSO tab, Enter the following in the fields:
   • IdP Entity ID: Enter your Hudu URL, e.g. https://docs.mywebsite.com
   • SP Identity ID: Enter your Hudu URL, e.g. https://docs.mywebsite.com
   • ACS URL: Enter https://docs.mywebsite.com/saml/consume
   • Sign on URL: Enter https://docs.mywebsite.com
   • Default Relay State: You can skip filling this in.
   • SAMLSubject NameID: Email
   • Signature Algorithm: RSA-SHA1
   • SAMLSubject NameID Format: Choose EmailAddress
   • Logout URL: Enter a URL where Hudu can redirect users after they sign out.
   • Make sure to replace docs.mywebsite.com with your URL and subdomain. There is also no trailing slash at the end of the URL.
5. Assign a user group with users that have MATCHING emails in Hudu.

Configuring the Fingerprint

1. In order to get the fingerprint, go to https://developers.onelogin.com/saml/online-tools/x509-certs/calculate-fingerprint.
2. Paste in the certificate from the Setup Instructions.
3. Use sha1 as the algorithm.
4. Copy the fingerprint. It should look like: 

   b909502ee82ae32433e6f83886b11d4277a32a7a

Configuring Hudu

- SAML Issuer URL: Needs to be the exact same as the IDP Identity ID you configured in Jumpcloud

- SAML Login and Logout - Copy the IDP URL from JumpCloud and paste in both

- SAML Fingerprint - Grabbed from the previous step

- SAML Certificate - Download from Jumpcloud and paste in. Make sure there is no extra spaces.
