NIS can host an
ethers table which can be used to manage DHCP configuration files for systems based on their platform, operating system, DNS domain, and MAC address — all information stored in host entries in IdM.
In Identity Management, each system is created with a corresponding
ethers entry in the directory, in the ou=ethers subtree.
This entry is used to create a NIS map for the
ethers service which can be managed by the NIS compatibility plug-in in IdM.
To configure NIS maps for
Add the MAC address attribute to a host entry. For example:
[jsmith@server ~]$ kinit admin
[jsmith@server ~]$ ipa host-mod --macaddress=12:34:56:78:9A:BC server.example.com
Add a line for the
ethers service, and set it to use LDAP for its lookup.
Check that the
ethers information is available for the client.
[root@server ~]# getent ethers server.example.com
