Bug.  Feel free to open a PMR.

If you want to stop authentication using TESTUSER, remove its password 
(ALTUSER TESTUSER NOPASSWORD).  Then it can't be used as an authenticator 
in ANY interface (including RACROUTE REQUEST=VERIFY), it can never be 
revoked due to invalid password attempts, and isn't subject to password 
expiry rules.  This effectively turns it into AUTOONLY without having to 
mess with the directory.
