[cvsnt] Can´t authenticate

[Guido Dappert]

Hello

I try  first time to bring CVSNT to run and I have large problems.
I have:
Windows 2000 Prof SP3
Install CVSNT 2.06 like step by step manual
Make Directories cvsrepo and cvstemp and one user have all rights on 
this directories
I make cvsrepo/test too and cvsnt initialize this directory 
(cvsrepo/test/CVSROOT)
after restarting service and reboot I try "set 
cvsroot=:sspi:<computername>:/test" and
cvs ls -l -R

Then comes the following message: cvs [ls aborted]: Can´t authenticate - 
server and client cannot agree on an authentication scheme (got ´´)

In install dir still exist the sspi_protocol.dll !

I try the complete weekend to run cvsnt without any progress. I hope 
that someone on this list has an Idea !

Thank you !
