Single Sign on allows us to know exactly which user is connected to PrimaryChat. Why is this important? It is important because with PrimaryChat we need to ensure it is only teachers/pupils that can chat to other teachers/pupils from the same school.
Currently the only Single Sign on system that works at an organizational(school) level is Shibboleth. Shibboleth is usually provided by your Local Authority however if this is not available to you then your school can use PrimaryLogon which is a beta labs service we currently offer.
