rpc.yppasswdd must be running on the NIS master server
  to allow users to change information in the password file.
The options are as follows:
  - -ddirectory
- Change the root directory of the password file from
      “/” to
      directory. It is important to create the binary
      database files (pwd.db and spwd.db) when using this switch or the password
      change will fail. The databases need to be created only once with the
      following command:
    
    pwd_mkdb -d directory
      directory/etc/master.passwd
 
- -noshell
- Don't allow changes of the shell field in the passwd file.
- -nogecos
- Don't allow changes of the gecos field in the passwd file.
- -nopw
- Don't allow changes of the password in the passwd file.
- -marg1 [arg2 ...]
- Additional arguments to pass to make in
      /var/yp.
 
  - /etc/passwd
-  
- /etc/master.passwd
