AFAIK there is no administrative setting to achieve this with only one
domain. I think it would be best to use multiple domains (say --portbase
10000, 11000 and so on) with different admin user names and passwords.
Domains are completely isolated from each other. Of course each domain
brings with it some overhead like memory requirements and so on.
The command to do this is:
asadmin create-domain --user admin1 --portbase 10000 admin1domain
