When running a build from Hudson, I'm getting: "Empty password used - try 'cvs login' with a real password"

Everything was working great with the build. Then this started popping up after the admins did some maintenace.

[workspace] $ "C:\Program Files\CVSNT\cvs.exe" -q -z3 update -PdC -D "Monday, August 23, 2010 12:00:52 PM UTC" Empty password used - try 'cvs login' with a real password

I've verified that CVS is working fine, and the acco开发者_开发技巧unt used to access CVS is working properly, and there were no code checkings that caused the issue.

Was your CVS application updated that Hudson is using? Was Hudson updated? Find out what your administrators did before you do any further troubleshooting.
