Help with Active Directory Integration and kerberos

Question

Hello,
I’m encountering a bug preventing me to use Active Directory integration with kerberos :
Our domain name is CORP.DOMAIN.COM.
When we request the GC in this domain :
bash-3.00# nslookup -query=any gc.tcp.corp.domain.com
Server: 1.2.1.6
Address: 1.2.1.6#53
** server can't find gc.tcp.corp.domain.com: NXDOMAIN
there is no answer.
But when we request without corp, we find the servers :
bash-3.00# nslookup -query=any gc.tcp.domain.com | grep sis
gc.tcp.domain.com service = 0 100 3268 serveur02.corp.domain.com.
gc.tcp.domain.com service = 0 100 3268 serveur01.corp.domain.com.
bash-3.00#
Is-it possible to add the possibility to enter the domain name where reside the gc.tcp ?
Thank you.

Hello
the domain.com domain exist, but it's not our domain.
so, when I put domain.com, it search with no result (nothing appends).
our kdc.conf :
[kdcdefaults]
kdc_ports = 88,750
[realms]
CORP.DOMAIN.COM = {
profile = /etc/krb5/krb5.conf
database_name = /var/krb5/principal
admin_keytab = /etc/krb5/kadm5.keytab
acl_file = /etc/krb5/kadm5.acl
kadmind_port = 749
max_life = 8h 0m 0s
max_renewable_life = 7d 0h 0m 0s
default_principal_flags = +preauth
krb.conf
[libdefaults]
default_realm = CORP.DOMAIN.COM
default_checksum = rsa-md5
[realms]
CORP.DOMAIN.COM = {
kdc = dc01.corp.domain.com
kdc = dc02.corp.domain.com
[domain_realm]
.corp.domain.com = CORP.DOMAIN.COM
corp.domain.com = CORP.DOMAIN.COM
in every domain, I think the GC are in corp.domain.com. but in my company, it's in domain.com...
Thank you,
