Severity: 3-Major
The OAuth protocol requires that the APM perform a loopback call to itself in order to pull details of a user. The packets sent by APM when sent over _loopback VLAN are being rejected by the default AFM rule. The _loopback is a non-configurable VLAN in firewall rules.
The OAuth virtual server is not working.
-- APM is enabled. -- AFM is enabled.
The _loopback is a non-configurable VLAN in firewall rules. Recommended workaround is to block all user-configured VLANs in the penultimate rule and then allow all in the last rule. This is less than ideal and would be prone to user error.
