# Setting up MIRACL Trust SSO as an Identity Provider Within G Suite
These instructions are up-to-date at the time of writing, but you should refer back to the G Suite page on SAML IdP access to check for any changes. We cannot guarantee the accuracy of our SP-specific guidance.
Log in to the GSuite Admin Console and go to Security > Setup Single Sign On. Note that for the above link to take you to the correct page, you need to have previously logged in to a valid G Suite account.
Complete the fields as below:
- tick the Setup SSO with third party identity provider checkbox
http://<yourssoip>/ssoin the Sign-in page URL field
https://accounts.google.com/Logoutin the Sign-out page URL field
- under ‘Verification certificate’, upload a file containing the contents of
the ‘public_certificate’ entry from the idp section of your sso
configuration in the

# Configuring a G Suite SP Profile With MIRACL Trust SSO
sp: google: description: Google G-Suite Services name: G-Suite relay_state: "" login_url: https://mail.google.com/a/example.com logout_url: https://accounts.google.com/Logout metadata: >- <?xml version="1.0" encoding="UTF-8"?> <!-- google doesnt provide a link to download its sp metadata, so this is hand-crafted --> <md:EntityDescriptor xmlns:md="urn:oasis:names:tc:SAML:2.0:metadata" entityID="google.com"> <md:SPSSODescriptor WantAssertionsSigned="true" protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol"> <md:NameIDFormat>urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified</md:NameIDFormat> <md:AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://www.google.com/a/example.com/acs" index="0"/> </md:SPSSODescriptor> </md:EntityDescriptor> sign_response: true sign_assertion: true encrypt_assertion: false authorize: - - email: ^[^@]+@example.com$ profile: attribute: empty
Note that the name under which the SP is registered in the sp section is used to create your IdP-initiated login url, i.e.
For login_url your specified domain should replace ’example.com’. This also needs to be changed in the Location parameter in the above metadata. The logout_url is the standard url which G Suite makes available for SAML IdPs to use.
Note that, if you are using JSON format for your config file, the handcrafted metadata above must be saved as an xml file; then converted to a single line with the " characters escaped with \ to meet the json structure requirements. This can be achieved by running the following command on the e.g. metadata.xml file:
echo -e "\n"$(cat metadata.xml | tr -d '\n' | sed -E 's/"/\\"/g')"\n"
The contents then are output in the terminal in a format that can be pasted into the metadata field of a JSON file.
In the authorize subsection, you can control what users are allowed to attempt login by following one or both of the below steps:
- Call up an LDAP setup from an
ldap.yamlfile stored in
- Configure a regex list of email addresses/domains. The above config shows
an example of how you would use
email: ^[^@]+@example.com$to only allow users from a certain email domain to login.
Note that if this is not set correctly, you receive ‘unauthorized user’ messages.
For more detailed info on using LDAP, API and/or regex to control authorized users, please see the authorization menu section.
- Call up an LDAP setup from an
Save and close the file.
In your /etc/miracl-sso/config.yaml file make sure you add
google.yamlto the list of ‘includes’:
includes: - core.yaml # service providers - service_providers/google.yaml
As always after config changes, restart the server.
Now your service is configured, you can visit
https://<yourssoip>/servicesto log in to the service using IdP-initiated login, or visit the G-Suite login page and SP-initiated login are triggered automatically.
You are able to login using the in-browser PIN pad or with the MIRACL Trust app. When logging in to your SSO service for the first time you are asked to register an email address so as to confirm your identity and register you as a user.
