[18 March 2012]An upgrade to the Single Sign On (SSO) service will take place at 08:30 on Tuesday 20 March.
This will result in a 5 minute interruption to the service. All services which use Single Sign On will be affected as the SSO service manages the authentication (log in) for a significant number of web based services (see image below).
Please note that the upgrade will break existing connections to services at that time and it will be necessary for you to sign back into services.
IT Services apologises for the inconvenience caused by this work.
