Configuring DNS Mapping on the Windows Domain Controller

• Configure valid forward and reverse DNS mapping for the computer systems in your domain.

  For example OpenSSO Enterprise and the Kerberos Domain Controller must have proper A (IP-Name lookup) and PTR (Reverse IP-Address lookup) records in the DNS database.

• If you use the /etc/hosts file instead of using DNS, all host names point to real, network-accessible IP addresses.

  For example, if the IP address for host1.example.org is 15.168.120.15, then the /etc/hosts file should contain the following entries:

  127.0.0.1 localhost openSSOhost 15.168.120.15 openSSOhost.example.com openSSOhost
