This should work, but I suggest adding:
SSPIUsernameCase lower
to make sure that the authentication is done with lowercase usernames -
otherwise SSPI would use both and then you might run into troubles if
you don't have the usernames in all casing in the svnaccess.txt file.

I think collab.net has some documentation on that. The mod_auth_sspi
website unfortunately has not much documentation..
