The pass-through (passthru) subsystem
can be used to replace the standard SkyVault user
database with a Windows server/domain controller, or list of servers, to
authenticate users accessing SkyVault. This saves
having to create user accounts within SkyVault.
The subsystem also supports optional NTLM Single Sign-On (SSO) functions for WebDav and the SkyVault Explorer and Share clients and direct CIFS authentication for the CIFS server. This method of authentication is much more secure than simple LDAP-based authentication or form-based authentication.
Note: Only NTLM v1 is supported in this configuration. As NTLMv2 has been
designed to avoid "man-in-the-middle" attacks, it would be impossible to
use in this pass through style.
