Single-Sign On (SSO) Authentication Loop With Azure AD

Problem

After attempting to "Sign In With SSO" and successfully authenticating with the Azure AD provider, the browser is re-directed back to the Platform9 UI login page.

Environment

• Platform9 Managed Kubernetes – All Versions

• Platform9 UI

• Authentication/Single-Sign On (SSO)

• Azure/Active Directory (AD)

Cause

SAML assertion is failing due to a missing Group Claim in the Azure application.

Resolution

1. Ensure a group claim exists under the "Attributes and Claims" section of the app, and that it matches the type "Security Group" with a Source attribute of "sAMAccountName".
