Dear all; Our UPKI-fed, the Japanese access management federation, regards that SSO for e-resources is the most persuasive merit of Shibboleth for librarians. However, we feel some difficulties to promote our federation only with this insistence. As same as in UK, there are many universities in Japan which use EZProxy as a tool of SSO for their libraries' e-resources. Considering Shibboleth as a tool for SSO, some of them claim that it is difficult to find any significant advantage over their EZProxy-based SSO systems. Then, how do you think the merit / demerit of... 1) Shibboleth-only SSO service, 2) Non-Shibbolized EZProxy-based SSO, 3) Hybrid SSO with Shibboleth and Shibbolized EZProxy ? Please show us your opinions. Best wishes; Hideaki ------------------------ NODA, Hideaki Chiba University Library Public service division.
