Remove the ypchfn/ypchsh stuff from passwd and leave just the
yppasswd support. The rest is moving into chpass.

|
||||
.Sh NIS INTERACTION
|
||||
.Nm Passwd
|
||||
has built-in support for NIS. If a user exists in the NIS password
|
||||
database but does not exist locally,
|
||||
.Nm passwd
|
||||
automatically switches into ``yppasswd'' mode. If the specified
|
||||
user does not exist in either the local password database of the
|
||||
NIS password maps,
|
||||
.Nm passwd
|
||||
returns an error.
|
||||
The following additional options are supported for use with NIS:
|
||||
.Bl -tag -width flag
|
||||
.It Fl y
|
||||
The
|
||||
.Fl y
|
||||
flag overrides
|
||||
.Nm passwd 's
|
||||
checking heuristics and forces
|
||||
it into NIS mode.
|
||||
.It Fl l
|
||||
When NIS is enabled, the
|
||||
.Fl l
|
||||
flag can be used to force
|
||||
.Nm passwd
|
||||
into ``local only'' mode. This flag can be used to change the entry
|
||||
for a local user when an NIS user exists when the same login name.
|
||||
For example, you will sometimes find entries for system ``placeholder''
|
||||
users such as
|
||||
.Pa bin
|
||||
or
|
||||
.Pa daemon
|
||||
in both the NIS password maps and the local user database. By
|
||||
default,
|
||||
.Nm passwd
|
||||
will try to change the NIS password. The
|
||||
.Fl l
|
||||
flag can be used to change the local password instead.
|
||||
.El
|
||||
.Pp
|
||||
When changing an NIS password, the user is required to provide
|
||||
the old password for authentication (the
|
||||
.Xr yppasswdd 8
|
||||
daemon requires the original password before
|
||||
it will allow any changes to the NIS password maps).
|
||||
This restriction applies even to the
|
||||
super-user: the only way for an administrator to override a
|
||||
user's NIS password is by modifying the NIS password maps on
|
||||
the master NIS server.
