I'm not sure that the auth cache holds that information, but I think you
can at least invalidate a particular auth cache entry by

 	1) Changing the user password (and save the previous hash)
 	2) Authenticate using the new credentials (and invalidate
 		the auth cache entry).  For example, you can just
 		do a manual connection on your dovecot server

 			x login someuser newpassword

 		This will replace the cache entry with a new one.

 	3) When you are ready to put the account back online, change the
 		password back to the original.  A password mismatch forces
 		a resync to your authentication system which will restore
 		the auth cache.
