Before enabling or disabling smart card login for iDRAC,
make sure that:
You have configure iDRAC permissions.
iDRAC local user configuration or Active Directory user configuration
with the appropriate certificates is complete.
NOTE: If smart card login is enabled, then SSH, Telnet, IPMI Over
LAN, Serial Over LAN, and remote RACADM are disabled. Again, if you
disable smart card login, the interfaces are not enabled automatically.
