> Let's see jhs as example:
> {code}RULE:[2:$1@$0](jhs/.*@.*REALM.TLD)s/.*/mapred/{code}
> That means principal has 2 components (jhs/myhost@REALM).
> The second column converts this to jhs@REALM. So the regex will not match on
> this since regex expects / in the principal.
> My suggestion is
> {code}RULE:[2:$1](jhs)s/.*/mapred/{code}
