Reports the current number of users whose Transparent Auto Logon authorization request is still outstanding, waiting on a response from AAA. This is effectively TAL's in-flight queue depth; a healthy system keeps this small and draining quickly, while a value that keeps climbing points at AAA being slow or unresponsive, which under cssgTalMaxPendingAuthReqs will eventually start causing SSG to drop new packets rather than queue them indefinitely. If cssgTalWaitingForAuthUsers climbs from a normal baseline of a few dozen up to several thousand and keeps rising, that's a strong sign the AAA server backing TAL has become a bottleneck.
