[cvsnt] cvs [update aborted]: Can't authenticate - server and client cannot agree on an authentication scheme (got '')

[Rob Green]

Using sspi i am now getting
"cvs [update aborted]: Can't authenticate - server and client cannot agree 
on an authentication scheme (got '')"
after i have upgraded to 2.0.26 on both the windows 2000 server and my 
windows xp client.  I upgraded after applying sp4 to w2k, so dont know if 
that broke it either..  I cant find any documentation on how to get sspi 
working (i dont remember how i originally did it), nor any info on the 
specific error.

my protocol_map.ini on the server looks like
;
; cvsnt protocol name mapping
;
[cvsnt]
;
; Use default Active Directory gserver, if installed
;
gserver = gserver_protocol.dll
;
;
; Comment above line and uncomment below to use MIT gserver
;
; gserver = gserver_protocol_mit.dll
;
;
; To disable a protocol change it to 'none'
;
; eg.
; pserver = none
;
;
; The following is for WSAD repository compatibility
;
extssh = ssh_protocol.dll


and my registry info is
