I have putty able to use gssapi on my Windows 7 x64 clients against kerberos logins for SSH. I.e. it forwards the ticket you get when you log in to windows. I can't figure out how to get tortiseSVN to do the same. I can get it to prompt me for my credentials every time I do ANYTHING and they work, by changing from neon to serf in the config file. But I need it to use the ticket so I don't have to continually type in my username and password. If Tortise can't do this, does anyone know of an svn client for Windows that does?
