Helpdesk calls cost an average of $25 to $62 a pop, with each person making an average of 3.3 “forgot my password” calls per year. So anytime you can reduce that number, you’re saving your company money. That’s part of what makes single sign-on solutions so useful.
How people define single sign-on (SSO) varies. It can mean using the same user credentials for different applications, but managed by a directory server (Directory Server Authentication). Some call this Basic SSO. SSO is also used to mean authentication where one sign-on generates a token or signed assertion that aware applications use to govern access.
