A guide for Tuple customers who want to use SAML SSO with OneLogin as the Identity Provider.
After signing in or creating your OneLogin account you’ll need to add a new SAML SSO application. Click on Applications > Applications in the top navigation bar.

In the search field, enter: SAML Test and select the SAML Test Connector (Advanced) from the results.

Fill in any required metadata, upload company logos you’d like to use, and save the new application.

After saving, click on Configuration in the left-hand sidebar.

Fill in all the fields circled in red.

Next, head to the Parameters section in the side bar and find the plus button to add new fields.
These fields will be sent along in the SSO response. There are three fields that Tuple requires in order to work: email, first_name, and last_name.

When adding these new fields, ensure that the checkbox Include in SAML Assertion is checked.

Repeat for first_name and last_name.

Once you’re finished with adding the required parameters the screen should look like:

Navigate to the Settings tab of the team management dashboard. Note: Only Team Owners have access to this page, so you will need to be Team Owner to access this page. If you need to find out who the Team Owner for your team is, view your profile.
