In the early stage of SL, we used  the normal procedure of adding nfs-shares to /etc/fstab on NFS clients. This method is fine when you have only a few shares, and a few clients, but a fully grown SL-network, with a large number of clients and a large number of shares _needs_ automount. AS we have chosen to use LDAP over NIS, the shares should be defined in LDAP. 

Automounting of home0 was enabled by default at 2003-09-22 14:30. Some documentation is at http://bugs.skolelinux.no/show_bug.cgi?id=309

Here is a roadmap on what to do when upgrading an existing installation. 

First you need to add some basic entries to your ldap tree. 

this is done by running 
 /etc/init.d/slapd stop         # Stopp the running server
 slapadd -l /etc/ldap/autofs.ldif  # only do this if the server succesfully stops
 /etc/init.d/slapd start        # start the server again

then, from a client, try to run this command: 
 . /etc/default/autofs
 ldapsearch -LLL -h $LDAPSERVER -b $MASTERDN \
      -x '(objectClass=automount)' cn automountInformation

the output should be
 dn: cn=/skole,ou=auto.master,ou=Automount,dc=skole,dc=skolelinux,dc=no
 cn: /skole
 automountInformation: ldap:ou=skole,ou=Automount,dc=skole,dc=skolelinux,dc=no

move the old /skole out of the way 
 mv /skole /skole.org

move the the file /etc/auto.master out of the way:
 mv /etc/auto.master /etc/auto.master.org

Make sure there is a line
 HOST ldap
in /etc/ldap/ldap.conf

then you should edit the file /etc/default/autofs to enable autofs
change the line 
 AUTOFS_ENABLED=false
into
 AUTOFS_ENABLED=true

Then start autofs with the command
 /etc/init.d/autofs start 

If things fail, please run 
 /usr/lib/debian-edu-config/testsuite/ldap-server
on the server, and on the client: 
 /usr/lib/debian-edu-config/testsuite/ldap-client

you should have debian-edu-install version 0.594 or greater for this

What to do if you want to add a new share:
lets say you want to add a new share /skole/tjener/home1
create a file calle autofs-home1.ldif with content: 
 dn: cn=home1,ou=tjener,ou=skole,ou=Automount,dc=skole,dc=skolelinux,dc=no
 objectClass: top
 objectClass: automount
 cn: home1
 automountInformation: -rw,rsize=8192,wsize=8192,intr tjener:/skole/tjener/home1
 description: /skole/tjener/home1 mount point

then add the content by running 
 /etc/init.d/slapd stop && slapadd -l autofs-home1.ldif && /etc/init.d/slapd start


Good Luck
