You have the ability to use Secure Socket Layer (SSL) certificate with your single sign on authentication processes. You can ensure each of your users is properly authenticated against web servers, email servers, database servers and LDAP directory servers. Each certificate you create contains the necessary information to perform the authentication processes without prompting the user to reenter their user name and password multiple times.
SSL Options Are Available for Operations Conducted over the Internet When Using Single Sign on Authentication
Another type of SSL process you can use with single sign on authentication is for website authentication and data encryption. These operations are often conducted over public networks where security is lax. By using SSL you are able to obtain a secure method for connection to websites and sending data over the internet. You are also able to reduce your risks about problems of being hacked by unauthorized users.
