|
|
|
.Tn NIS
|
1993-04-27 09:10:23 +04:00
|
|
|
subsystem allows network management of passwd and group file
|
1994-11-14 09:30:36 +03:00
|
|
|
entries through the functions
|
|
|
|
|
.Xr getpwent 3
|
|
|
|
|
and
|
|
|
|
|
.Xr getgrent 3 .

|

1994-11-14 09:30:36 +03:00

also provides hooks for other client programs, such as
|
|
|
|
|
.Xr amd 8
|
|
|
|
|
and
|
|
|
|
|
.Xr bootparamd 8 ,
|
|
|
|
|
that can use

1999-01-16 17:16:41 +03:00
|
|
|
.Tn NIS

maps.

|
|
|
|
.Pp
|
2001-02-08 16:40:53 +03:00
|
|
|
Password maps in standard YP are insecure, because the pw_passwd
|
2001-06-19 16:52:20 +04:00
|
|
|
field is accessible by any user. A common solution to this is to
|
2001-02-08 16:40:53 +03:00
|
|
|
generate a secure map (using
|
|
|
|
|
.Dq makedbm -s )
|
|
|
|
|
which can only be accessed by a client bound to a privileged port.
|
|
|
|
|
To activate the secure map, see the appropriate comment in
|
|
|
|
|

.Sh HISTORY
|
1996-08-09 18:40:28 +04:00
|
|
|
The
|
1999-01-16 17:16:41 +03:00
|
|
|
.Tn NIS
|
1996-08-09 18:40:28 +04:00
|
|
|
client subsystem was originally written by Theo de Raadt
|
|
|
|
|
to be compatible with Sun's implementation. The
|
1999-01-16 17:16:41 +03:00
|
|
|
.Tn NIS
|
1996-08-09 18:40:28 +04:00
|
|
|
server suite was originally written by Mats O Jansson.

|
|
|
.Sh BUGS
|
|
|
|
|
If
|
|
|
|
|
.Xr ypbind 8
|
|
|
|
|
cannot find a server, the system behaves the same way as Sun's code:
|
|
|
|
|
it hangs.
|
|
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Sq secure map
|
|
|
|
|
feature is not compatible with non-BSD implementations as found
|
|
|
|
|
e.g. in Solaris.
