Single sign-on at ETH
A workshop on the topics of single sign-on, AAI and application integration was recently held with representatives of the Library, Rectorate, ITS-Academic Management Applications (BI) division, LET and ETHis. Since the SWITCH infrastructure AAI is apparently being widely used at ETH, ITS-Acad.Mgmt Ap. accordingly decided that implementation stages in 2011 and 2012 will focus on development of educational applications coordinated with development of the new nethz Admin application.
