The requirements for using the Solstice AutoClient software are:
An entry for your host name and user name in root's .rhosts file on the NIS master server if the server is running the Solaris 1.x OS Release. If the NIS master server is running the Solaris 2.x OS Release and Name Services Transition Kit 1.2 software, this entry is not required as long as Solstice AdminSuite is also installed.
Running ypbind with the -broadcast option, which is the default form, if you want to manage NIS map information in domains other than your own.
In order to manager NIS map information in domains other than your own, the other NIS domain masters need to be on directly attached networks.
