credentiaslttl does not mean what you seem to think it does.
It is just an optimization to reduce the amount of lookups to the
helper. How often they are *checked*.
In your other thread you showed this report:

Think of credentialsTTL ("Check TTL") hitting 0 as the start of that
"grace period". The cache garbage collection (Cache TTL) defines the end
- when the credentials are completely forgotten by Squid.
As you can see there is already a "grace period" of 3540 seconds on
As Emmanuel said you can fake a sort-of logout by having a custom helper
pretend the credentials have expired suddenly. But that is something
your helper does, not this TTL.
Keep in mind that while Squid is awaiting your helper response all new
HTTP requests using those credentials will be queued up waiting for its
response. When the helper responds its answer will be applied to all
those queued and all future requests until the next credentialsttl
