Description

Let's see jhs as example:

RULE:[2:$1@$0](jhs/.*@.*REALM.TLD)s/.*/mapred/

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

RULE:[2:$1](jhs)s/.*/mapred/
