Single Sign-On (SSO) must be enabled before a connection with an SSO provider can be configured. Single Sign-On is enabled from the Single Sign-On page.
Before SSO can be enabled, all R365 users must have unique email addresses. If duplicate email addresses are found, the users are listed for review and resolution.
Once SSO is enabled, unique email addresses are permanently enforced. Enabling SSO does not change the user login experience until a connection with an SSO provider is successfully configured. Learn more about connecting to Okta or Microsoft Entra (Azure).
Security
Users must have the following permission to enable SSO:
Administration → Single Sign-On (SSO) → Create/Edit Single Sign-On
These permissions can be added to custom user roles or individual users. The Permission Access report can be used to determine which user roles or users already have these permissions assigned. For more information, see User Setup and Security.
