Set up Single Sign-On (SSO) for Allium using your identity provider (IdP) via SAML.

​
Step 1 — Create a SAML Application in Your IdP

  1. In your IdP’s admin dashboard, create a new SAML 2.0 application/integration.
  2. When prompted for SAML configuration details, enter the following:
    FieldValue
    Single sign-on URL (ACS URL)https://allium-firebase.firebaseapp.com/__/auth/handler
    Entity ID (Audience URI)https://app.allium.so
    Be careful — do not include a trailing slash in the SSO URL or Entity ID.
  3. Complete your IdP’s setup flow.
    If your IdP supports it, you can restrict access by assigning specific groups or users to the application.

​
Step 2 — Locate Your SAML Metadata

After the application is created, your IdP will provide the following values:
FieldDescription
Identity Provider Single Sign-On URLAlso called Login URL or SAML Endpoint
Identity Provider IssuerSometimes called Entity ID
X.509 CertificatePublic certificate for SAML signing
These are often available under a SAML Setup Instructions, Metadata, or Configuration page in your IdP.

​

  2. Paste each of the three values from your IdP into the matching fields.
  3. Save your changes.
