求翻译：使用基于SAML的单点登录，单点登录服务器成为惟一可以接受安全凭证信息的场所，由于不必到处传递安全凭证信息，从而增强了整个系统的安全性。是什么意思？

Use saml-based single point of login, single sign-on server to become the only place that can accept a security certificate information, do not have to be passed around the security certificate information, thereby enhancing the security of the entire system.

正在翻译，请等待...
