To provide a seamless user handling, IFS, AD FS and SAML Session Provider must be configured consistently. See "Users in M3" in M3 Core Installation Planning Guide.
When ION is installed, the user property IFS Person ID is added to IFS. This property must be populated with a unique value for each user, corresponding to the M3 user.
Important: A user that has the Person property set to MVXSECOFR must be configured and able to log on, in order to configure M3 BE.
On a high level, these steps must be completed for users to get the correct names for accessing M3 BE. Detailed instructions for each step are found in subsequent chapters.
