The version of su you're using (from shellutils) isn't part of the shadow password suite. It's smart enough to use shadow password functions if it finds them in the library, which it does, but other shadow features (ENV_SUPATH, SU_WHEEL, MD5 passwords) aren't available.
If you want them, you need to replace shellutils's su with the shadow-su package. It should be in the distribution somewhere; I can't say where, I don't use it. --Galen -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
