SAMBA3.5pre2-Does map untrusted to domain work?

Tue Jan 19 13:53:10 MST 2010

Hello, Steven.
Did you ever get a chance to look at this?  I just tried this on the latest 3.4.5 build but it still seems to be doing the same
thing in that I have to pass the domain with the username in order for SAMBA to authenticate.  Meaning,
the "map untrusted to domain" does not seem to revert to the previous behavior.  With that enabled, the logs
still show:

Got user=[username] domain=[pcname] workstation=[pcname]

Thanks for the help!
