RE: "Replacing" an attribute's value with "nothing"

["Kevin Hicks" <Kevin.Hicks@drintuit.dr.avaya.com>]

Here are a couple of ideas...

We have an application level replace function that is used by all our other application code to do ldap replaces.  If it is passed a blank value, instead of doing a replace it does a delete.

Or

In some cases, we always want the attribute to be present even if it isn't set.  In those cases, we use -1 to mean the attribute is not set.
