We are in the process of installing our first Landmark application and in doing so will also be moving ISS and Azure for single sign on. We have run into issues using the UPN (email) when there is a change to the email address - our UPN is not correctly assigned until after an Outlook 365 license is obtained and/or when employees have a name change. Infor provides the ability to use the ActorId for authentication (listed in the dropdown) so we configured Azure to pass the employee id in ActorId - our employee id's never change so thought this would be a better option than trying to use email address that can change. We made the change to Azure, changed the SSOP to employeeid, tested and it appeared to make the authentication but we got a security related error in regard to LSF. Has anyone attempted this authentication method and if so, what configuration change needs to be made to LSF to login with ActorId? Thank you!
