did everything the book says, i.e. removed the authentication files from .subversion/auth, and explicitly set the relevant config parameters to 'yes' even though this is a default, and yet the shell svn commands ask for password each time. The repository is on cvsdude.com, the client is linux. I also use the subclipse plugin that caches the password ok.

I vaguely remember that when I started working with it, the command asked interactively if I wanted to save clear password, and I said no. Can this choice be stored somewhere and take precedence over the configuration? Thanks!
