A question about DNS SRV record

Hi all,
The behavior of our DNS(BIND 8.2.2) as part of a network management app.
should be like this:
Any request coming to the DNS should be resolved to it's own IP address.
(If user is in non-authenticated VLAN and when ever user tries to access
any thing through the browser, user is directed to a logon page which will
be displayed by a webserver running on our DNS. Once after successful
authentication, user will be put into a valid VLAN )
We have a simple configuration for bind:
snippet from named.conf:
zone "." {
type master;
file "iammaster"
};
snippet from iammaster file:
*.com. IN A ipaddress of our dns
* IN A ipaddress of our dns
This configuration worked well and the wild card (*) resolution worked for
all the domain names for the last 2 years.
Now we have to make this DNS (SRV) service records aware to support
Microsoft's AD domain controller.
Required behavior should be like this:
Resolve all the queries to it's own IP except the service requests (SRV)
like _ldap._tcp.dc._msdcs.mydomain.cisco.com
I added these SRV records to the zone file, but still client can not find
the AD domain controller.
nslookup works as expected.
Your help is very much appreciated.
Thanks,
Sanapala
