Restricting access to the master server

For security reasons, you may want to restrict access to the new master NIS server to a smaller set of users than those defined in its existing /etc/passwd file. To do this, first make sure the existing passwd file does not contain the NIS escape entry ``+''. Then, perform one of the following:

• If you need to remove many users, edit the master server's /etc/passwd and /etc/shadow files to remove the entries for the undesirable users. Then run the creatiadb(1M) command to update the Identification and Authentication (I&A) database.

• If you need to remove only a few users, run the userdel(1M) command to remove the entries for each undesirable user (the Identification and Authentication (I&A) database will be automatically updated).
