Alright, now I've answered at least one of my own questions. I have located the Oracle documentation explaining that you can only have on ACL per host (see Usage Notes at http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10577/d_networkacl_adm.htm#BABDIGJC) Now I still would like to know how I can add a user who to have access to only one host, when the host's ACL is assigned to multiple hosts.
