From the field: Three gotchas when migrating applications from AD FS to Entra
- When migrating applications from AD FS to Entra, some applications may use a federation protocol like Shibboleth which is not supported in Entra.
- Organizations can choose from solutions like Microsoft Entra ID with Cirrus Bridge or AD FS and Shibboleth to address the protocol compatibility issue.
- Issues can arise if applications use outdated attributes like sAMAccountName instead of userPrincipalName for Name ID, affecting user sign-in and backend data consistency.
- Updating the back-end of AD FS-integrated applications to use userPrincipalName attribute can prevent new user creation and ensure proper settings during migration.
- User assignment in Entra does not support group nesting, which can be a challenge when migrating from AD FS where group nesting was allowed.
- To overcome group nesting issues, groups must be flattened by adding specific members of subgroups to the primary group before migration to Entra.
- Careful consideration and planning are essential to address these gotchas and ensure a smooth transition from AD FS to Entra for applications, services, and platforms.
- Addressing protocol compatibility, attribute mapping, and group nesting challenges beforehand can help in minimizing disruptions during the migration process.
- It is recommended to review claims issuance rules, attribute mappings, and group configurations thoroughly to mitigate potential issues during the migration.
- Proactive identification and resolution of these gotchas can contribute to a successful and efficient migration from AD FS to Entra.
- Overall, thorough planning, communication with stakeholders, and testing are crucial for a successful migration project involving moving applications from AD FS to Entra.
