4.6. Configuring an IdM client to use IdM servers in the same location

Identity Management (IdM) servers are assigned to DNS locations as described in Assigning an IdM server to a DNS location using the IdM Web UI. Now you can configure the clients to use a DNS server that is in the same location as the IdM servers:

If a DHCP server assigns the DNS server IP addresses to the clients, configure the DHCP service. For further details about assigning a DNS server in your DHCP service, see the DHCP service documentation.
If your clients do not receive the DNS server IP addresses from a DHCP server, manually set the IPs in the client’s network configuration. For further details about configuring the network on Red Hat Enterprise Linux, see the Configuring Network Connection Settings section in the Red Hat Enterprise Linux Networking Guide.

注意

If you configure the client to use a DNS server that is assigned to a different location, the client contacts IdM servers in both locations.

例 4.1. Different name server entries depending on the location of the client

The following example shows different name server entries in the /etc/resolv.conf file for clients in different locations:

Clients in Prague:

nameserver 10.10.0.1
nameserver 10.10.0.2

Clients in Paris:

nameserver 10.50.0.1
nameserver 10.50.0.3

Clients in Oslo:

nameserver 10.30.0.1

Clients in Berlin:

nameserver 10.30.0.1

If each of the DNS servers is assigned to a location in IdM, the clients use the IdM servers in their location.
