Doing a reverse DNS lookup on Ubuntu returns:
root@adclient01:~# host 192.168.122.250
250.122.168.192.in-addr.arpa domain name pointer adc01.

While on Fedora is returns the name with the domain:
root@localhost-live ~]# host 192.168.122.250
250.122.168.192.in-addr.arpa domain name pointer adc01.
250.122.168.192.in-addr.arpa domain name pointer adc01.warthogs.biz.

I suspect that the client being unable to associate the domain name with the domain of the AD server makes it fail. It's very likely that moving the DNS to the AD server will fix this.
