Single Sign-on via SAML
SAML is a single sign-on standard that is widely used and implemented by CompleteFTP Enterprise MFT. It means that users need to sign-in only once, to a server known as the Identity Provider (IDP). A service provider (SP) that requires users to be authenticated can set up a trust relationship with an IDP, and the IDP tells the SP that a user is permitted to login.
Delegate Authentication of Users
CompleteFTP Enterprise MFT can be configured as a SAML SP (Service Provider). It can delegate authentication to a IDP but it can't itself act as an IDP. One IDP that has been tested with CompleteFTP is OneLogin.
