Differences between Single Sign On and Password Synchronization
Single Sign On (SSO) and Password Synchronization are two functions that were implemented in EP Hard Disk 7.0. Customers often confuse these two functions, expecting password synchronization to automatically occur if only SSO is enabled in the EP Hard Disk User Program.
The EP Hard Disk Administrator must enable both SSO and password synchronization during the setup of the EP Hard Disk User Program in order for users to achieve password synchronization to their Windows and network logins.
A comparative analysis of SSO and Password Synchronization is attached to further clarify the differences between these functions. This is a generic document intended to describe the conceptual differences between these functions which can be implemented using various methods.
SSO has been implemented in EP Hard Disk by using a GINA specific to EP Hard Disk (EPHDgina) and chaining this GINA to the Windows. network, and other user authentication GINAs. Single Sign On (SSO) provides the ability to pass authentication from one system to the next at the time of logon.
Password synchronization has been implemented in EP Hard Disk versions 7.0 - 7.1.3 using a password filter that catches the password change when it is made locally and changes the EP Hard Disk password. Password synchronization has been implemented in EP Hard Disk 7.1.4 and later using a Credential Manager in place of the password filter. The Credential Manager functionality is more robust and includes the capability of catching password changes that are made at the network server (Active Directory or Novell eDirectory/NDS) and synchronizing the EPHD password.
