How to set configutil params to null

Here's a silly little question that I'm pondering: How do you set a configutil parameter to null?

Many parameters that can be set by configutil are null by default. An example is the single sign-on parameter local.webmail.sso.amnamingurl. You set this parameter to your Access Manager to enable SSO.

Now what if you wanted to disable SSO. Ostensibly, you would reverse the procedure and return local.webmail.sso.amnamingurl to null. But what syntax should I use so as not to confuse LDAP

configutil -o local.webmail.sso.amningurl -v ""

or is something else preferred?
