Description (partial)

As per documentation its not recommended to enable dot1x along with port-security while in MAB environment customers may need to have both features enabled to control amount of devices connected to the port.

This is an enhancement request to have both those feature fully supported.

IEEE 802.1x Authentication with Port Security
In general, Cisco does not recommend enabling port security when IEEE 802.1x is enabled. Since IEEE 802.1x enforces a single MAC address per port (or per VLAN when MDA is configured for IP telephony), port security is redundant and in some cases may interfere with expected IEEE 802.1x operations.
