lamdaemon.pl is used to modify quota and homedirs
on a remote or local host via ssh.
If you want wo use it you have to set up some
things to get it to work:

1. Setup values in LDAP Account Manager
   * Set the remote or local host in the configuration
    (e.g. 127.0.0.1)
   * Path to lamdaemon.pl, e.g. /srv/www/htdocs/lam/lib/lamdaemon.pl


2. Set up sudo
   The perl script has to run as root. Therefore we need
   a wrapper, sudo.
   Edit /etc/sudoers on host where homedirs or quotas should be used
   and add the following line:
   $admin All= NOPASSWD: $path
   $admin is the adminuser from LAM and $path
   is the path to lamdaemon.pl e.g. "$admin All= NOPASSWD: /srv/www/htdocs/lam/lib/lamdaemon.pl"
   At the moment the password is a paramteter of lamdaemon.pl
   therefore you should disable logging so the password does not
   appear in any logfile.
   This can be done by adding the following line to /etc/sudoers:
   Defaults:$admin !syslog


3. Set up Perl
   We need some external Perl modules, Quota and Net::SSH::Perl
   To install them, run:

   perl -MCPAN -e shell
   install Quota
   install Net::SSH::Perl

   If your Perl executable is not located in /usr/bin/perl you will have to edit
   the path in the first line of lamdaemon.pl.


4. Test lamdaemon.pl
   There is a test-function in lamdaemon.pl. Please run lamdaemon.pl
   with the following parameters to test it:

   lamdaemon.pl $ssh-server $lam_path_on_host $admin-username $admin-password *test

   $ssh-server is the remote host lamdaemon.pl should be run on
   $lam_path_on_host is the path to lamdaemon.pl on remote host
   $admin-username is the name of the user which is allowed to run lamdaemon.pl
                   as root. It is the same user as in /etc/sudoers
   $admin-password is the password of the admin user
   *test is the command which tells lamdaemon.pl to test settings

   You have to run the command as the user your webserver is running, e.g.

   wwwrun@tilo:/srv/www/htdocs/lam/lib> /srv/www/htdocs/lam/lib/lamdaemon.pl \
     127.0.0.1 /srv/www/htdocs/lam/lib/lamdaemon.pl root secret *test

   You should get the following response:

     Net::SSH::Perl successfully installed.
     Perl quota module successfully installed.
     If you have not seen any error lamdaemon.pl should be set up successfully.


Now everything should work fine.
