Quest OpenSSH is a version of OpenSSH modified and packaged to provide default single sign-on capability for customers using Quest's Vintela Authentication Service (VAS) and/or Vintela Management eXtensions (VMX) products. Quest's version of OpenSSH defaults to authenticating users and hosts with GSSAPI. It works in conjunction with VAS, to allow secure shell single sign-on to Unix hosts joined to Active Directory domains.
