not all single sign-on , all with the ticket, such as using " reverse proxy " mode , you do not ticket.
For SAML, it is superfluous . Single Sign- emphasis on the existing system as little as possible of changes, the existing system , there are several with SAML? Almost no !

there is no master would this , such as online ! ! ! !

of course, some of our existing distribution system or use the ticket to achieve.
you may need to set up a single certification service , between services can also be certified through standard communication protocols to exchange authentication information in order to complete a higher level of single sign-on .
