 Name

    yppasswdd - server for modifying the Network Information Service (NIS)
    password file

 Syntax

    /etc/yppasswdd file [ -m arg1 arg2 ... ]

 Description

    yppasswdd is a server that handles password change requests from
    yppasswd(NC).  It changes a password entry in file, which is assumed to
    be in the format of passwd(C).  An entry in file will only be changed if
    the password presented by yppasswd matches the encrypted password of that
    entry.

    If the -m option is given, then after file is modified, a make(CP) will
    be performed in the directory /etc/yp.  Any arguments following the flag
    will be passed to make.

    This server is not run by default.  If it is desired to enable remote
    password updating for the Network Information Service, an entry for
    yppasswdd should be put in the /etc/nfs file of the host serving as the
    master for the Network Information Service passwd file.

 Example

    If the Network Information Service password file is stored as
    /etc/yp/src/passwd and password changes are to be propagated immediately,
    the server should be invoked as:

       /etc/yppasswdd /etc/yp/src/passwd -m passwd DIR=/etc/yp/src

    See /etc/nfs for the expected normal use of yppasswdd.

 Files

    /etc/yp/Makefile

 Notes

    Eventually, this server will be replaced with a more general service for
    modifying any map in the Network Information Service.
