<title>Advanced Network Manangement</title>
<para>
This section attempts to document peripheral issues that are of great importance to network
administrators who want to improve network resource access control, to automate the user
environment, and to make their lives a little easier.

<emphasis>How do I get 'User Manager' and 'Server Manager'?</emphasis>
</para>
<para>
Since I don't need to buy an <application>NT4 Server</application>, how do I get the 'User Manager for Domains',
the 'Server Manager'?
</para>
<para>
Microsoft distributes a version of these tools called nexus for installation
on <application>Windows 9x / Me</application> systems. The tools set includes:

<title>Network Logon Script Magic</title>
<para>
This section needs work. Volunteer contributions most welcome. Please send your patches or updates
to <ulink url="mailto:jht@samba.org">John Terpstra</ulink>.
</para>
<para>
There are several opportunities for creating a custom network startup configuration environment.
</para>
<simplelist>
<member>No Logon Script</member>
<member>Simple universal Logon Script that applies to all users</member>
<member>Use of a conditional Logon Script that applies per user or per group attirbutes</member>
<member>Use of Samba's Preexec and Postexec functions on access to the NETLOGON share to create
a custom Logon Script and then execute it.</member>
<member>User of a tool such as KixStart</member>
</simplelist>
<para>
The Samba source code tree includes two logon script generation/execution tools.
See <filename>examples</filename> directory <filename>genlogon</filename> and
<filename>ntlogon</filename> subdirectories.
</para>
<para>
The following listings are from the genlogon directory.
</para>
<para>
This is the <filename>genlogon.pl</filename> file:
<programlisting>
#!/usr/bin/perl
#
# genlogon.pl
#
# Perl script to generate user logon scripts on the fly, when users
# connect from a Windows client. This script should be called from smb.conf
# with the %U, %G and %L parameters. I.e:
#
# root preexec = genlogon.pl %U %G %L
#
# The script generated will perform
# the following:
#
# 1. Log the user connection to /var/log/samba/netlogon.log
# 2. Set the PC's time to the Linux server time (which is maintained
# daily to the National Institute of Standard's Atomic clock on the
# internet.
# 3. Connect the user's home drive to H: (H for Home).
# 4. Connect common drives that everyone uses.
# 5. Connect group-specific drives for certain user groups.
# 6. Connect user-specific drives for certain users.
# 7. Connect network printers.
# Log client connection

# Now connect Printers. We handle just two or three users a little
# differently, because they are the exceptions that have desktop
# printers on LPT1: - all other user's go to the LaserJet on the
# server.
