[Zope] Single Sign on

[David Orr]

I am currently building an intranet utilising Zope/Plone and plan on
authenticating users via LDAP (ldapuserfolder).  However I am now expected
to implement a "single sign on" system for the company which currently uses
NT domains to authenticate users.  

Has anybody had any experience in this?  I'm beginning to think that it may
be "easier" (short term at least) to just authenticate people via NT domain
and drop the ldap.  I will be very grateful for any advice.

cheers
