Students login with <a href="mailto:netID@live.kutztown.edu">netID@live.kutztown.edu</a> against AD and the intention is for them to do so with SSO as well. We have set the eduPersonPrincipalName attribute in AD to reflect the UPN of the Staff/Faculty and the Students. This appears to be causing some problem with one of the Service Providers that Staff/Faculty and Students are using. As long as the EPPN is <a href="mailto:netID@kutztown.edu">netID@kutztown.edu</a> the login works as expected, however with the EPPN is <a href="mailto:netID@live.kutztown.edu">netID@live.kutztown.edu</a> the auth works, but is redirected back to the SP’s login page.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Is it acceptable to have subdomains used in the EPPN attribute? <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>Dave<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:16.0pt;font-family:"Harlow Solid Italic"'>David A.
