Platform: Cisco ASA 8.2.1.
Please consider the log line below:
Dec 3 04:03:56 ciscoasa %ASA-7-715053: Group = mygroup, Username = jdoe, IP = 192.168.1.2, MODE_CFG: Received request for DHCP hostname for DDNS is: zzhostname!
Would it be possible in the ASA configuration, in some way, to *disallow* a user from connecting to the ASA if their hostname did not contain "zz" or some other arbitrary string? I know that the ASA can use a group policy to verify client OS and version, but we would like to device a way to block certain reported DDNS names.
