[KBA-79044] Interlock, Antipassback and Max Occupancy might not work properly in Security Center 22.214.171.124 and up
This article explains why Interlock, Antipassback and Max Occupancy might not work properly when running 126.96.36.199 and up.
If you have a reader-less door with an unlock schedule, this door does not lock when another door in the Interlock area is opened.
This occurs if there are reader-less doors or doors with single readers to exit the Interlock area.
Antipassback and Max Occupancy:
When a cardholder leaves and tries to re-enter an area where Antipassback hard and strict is in place and where there are doors with single readers to exit the area, access is denied due to Antipassback violation.
This occurs if the area has doors or turnstiles to exit with a single reader on any side.
This bug was introduced while doing the 188.8.131.52 performance improvements.
