Good afternoon, What are ports 80, 443 and 8443 primarily used for within the shibboleth system and on which side must they be opened(SP or IDP)? As far as I know, 8443 is used to transmit metadata as well as control attribute release. What are 443/80 for? Also, are there any more ports that must be opened in order for shibboleth to work? Best, Ken Ordona
