NAME

rpc.yppasswdd − server for modifying NIS password file

SYNOPSIS

/usr/etc/rpc.yppasswdd filename [ adjunct_file ] [ −nogecos ] [ −noshell ] [ −nopw ]

[ −m argument1 argument2 ... ]

DESCRIPTION

rpc.yppasswdd is a server that handles password change requests from yppasswd(1).  Unless an adjunct_file is specified, it changes a password entry in filename, which is assumed to be in the format of passwd(4).  filename is the password file that provides the basis for the passwd.byname and passwd.byuid maps.  This should not be confused with the server’s /etc/passwd file which controls access to the server.  In particular, this file should not contain an entry for the super-user. 

If an adjunct_file is specified or /etc/security/passwd.adjunct exists, this file will be changed instead of the filename. An entry in filename or adjunct_file will only be changed if the password presented by yppasswd(1) matches the encrypted password of that entry. 

This server is not run by default, nor can it be started from inetd(1M).  To enable remote password updating for NIS, then an entry for rpc.yppasswdd should be put in the /etc/rc file of the host serving as the master for the NIS passwd file. 

OPTIONS

−nogecos

−noshell

−nopw If these are given, then these fields may not be changed remotely using the passwd(1). 

−m If this option is given, then after filename or adjunct_file is modified, a make(1S) will be performed in /var/yp.  Any arguments following the flag will be passed to make(1S). 

EXAMPLES

If the NIS password file is stored as /var/yp/passwd, then to have password changes propagated immediately, the server should be invoked as

example% /usr/etc/rpc.yppasswdd /var/yp/passwd −m passwd DIR=/var/yp

FILES

/var/yp/Makefile

/etc/security/passwd.adjunct

/etc/rc

NOTES

The password file specified to rpc.yppasswdd cannot be a link.
