2.2.2.2. Examples

If your default realm was APACHE.ORG, but you also wanted to take all principals from ACME.COM that had a single component joe@ACME.COM, you would create this rule:
```
RULE:[1:$1@$0](.*@ACME\.COM)s/@.*//
DEFAULT
```
To also translate names with a second component, you would use these rules:
```
RULE:[1:$1@$0](.*@ACME\.COM)s/@.*//
RULE:[2:$1@$0](.*@ACME\.COM)s/@.*//
DEFAULT
```
To treat all principals from APACHE.ORG with the extension /admin as admin, your rules would look like this:
```
RULE[2:$1%$2@$0](.*%admin@APACHE\.ORG)s/.*/admin/
DEFAULT
```
