Custom SAML SSO

Use this guide when your provider supports SAML 2.0 but is not listed as a preset.

Provider setup

Create a SAML 2.0 application in your identity provider and configure the Lettermint service provider values from the SSO setup screen.

The provider should return an email address for the user. Lettermint uses the email address to match the managed team domain.

Lettermint setup

In the Lettermint SSO setup screen, choose Custom SAML and enter:

FieldDescription
DomainThe verified email domain that should use this provider.
Metadata URLThe IdP metadata URL, when available.
Entity IDThe IdP entity ID.
SSO URLThe IdP sign-in URL.
CertificateThe IdP signing certificate.

Use the metadata URL when your identity provider provides one. It reduces manual configuration and makes certificate rollover easier.
