This link, rather than pointing to a page within the MyIdentity portal would have taken the user to the appropriate webpage with instructions on how to complete a legal name change, based on the role(s) that SailPoint detects that user's having:
Anyone detected as an employee will be directed to a page maintained by HR with information on how to update legal name and/or sex
Anyone detected as a student, but not an employee, will be directed to a page maintained by the RO with information on how to update legal name and/or sex
Guest and affiliate users do not have Legal Names stored in the system, and no link will be displayed for them.
