Hi All, I am trying to set up my web.config file for single sign on. I have alreadyconfigured the Central Admin site to except single sign on.All of the info in red is what I have changed in the web.configs and machine.config files. I keep getting this error (in blue at the bottom of this post). Any help would be appreciated. If you have any questions, just let me know. These came from an MS support person who has ADFS running with MOSS'07.* Central Admin Page:o Click application management -> authentication providerso Click "Windows" for the selected web application.o Select Web Single Sign On radio button.o Enter "SingleSignOnMembershipProvider2" in the membership providersection.o Enter "SingleSignOnRoleProvide2" in the role provider section.* Change the web.config file for the central admin site:- register the membership provider and the role manager in theweb.config file for the central admin (so that the people picker on thecentral admin pages can correctly resolve the users).
