If you are supporting Solaris clients, you WILL need the 2307bis style automount schema, although Sun’s version is NOT identical to the one at http://people.redhat.com/nalin/schema/autofs.schema.
The following schema is from the HP’s site
dn: cn=schema
objectClasses: ( 1.3.6.1.1.1.2.16 NAME 'automountMap' DESC 'Automount Map information' SUP top
STRUCTURAL MUST automountMapName MAY description X-ORIGIN 'user defined' )
objectClasses: ( 1.3.6.1.1.1.2.17 NAME 'automount' DESC 'Automount information' SUP top STRUCTURAL
MUST ( automountKey $ automountInformation ) MAY description X-ORIGIN 'user defined' )
attributeTypes: ( 1.3.6.1.1.1.1.31 NAME 'automountMapName' DESC 'automount Map Name' EQUALITY
caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE X-ORIGIN 'user defined' )
attributeTypes: ( 1.3.6.1.1.1.1.32 NAME 'automountKey' DESC 'Automount Key value' EQUALITY
caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE X-ORIGIN 'user defined' )
attributeTypes: ( 1.3.6.1.1.1.1.33 NAME 'automountInformation' DESC 'Automount information'
EQUALITY caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE X-ORIGIN 'user
defined' )
Should also apply to Fedora DS http://www.ldapguru.com/modules/newbb/viewtopic.php?topic_id=1478&forum=24#forumpost5016

Instructions on how to create autofs mount entries for ldap and linux. First part deals with exporting /home for our user tux.
You should have your ldap server up and running. Root access to the server you want autofs to work on. Also that server should already be able to communicate with the ldap server for users/groups. You will need the perl script found here ol-schema-migrate.pl . And download the schema schema file mentioned above. You will also need to have nfs service on the server you want to export directories from. configuring nfs is beyond the scope of this document but an entry in the /etc/exports looks something like this
/home 192.168.1.0/16(rw,fsid=0,insecure,no_subtree_check,sync,anonuid=65534,anongid=65534)
Test from the command line that you can mount the /home directory. This helps eliminate suspects when things don’t work. You should also change our test user tux to a user in your ldap server.
The schema is now shipped with Directory Server Core as 60autofs.ldif
Now that we have our schema loaded we can now create our auto.supplier ou (Organizational Unit).
dn: ou=auto.supplier,dc=example,dc=com
ou: auto.supplier
objectClass: top
objectClass: automountMap
Now create a automount entry under auto.supplier for /home
dn: cn=/home,ou=auto.supplier,dc=example,dc=com
objectClass: automount
cn: /home
automountInformation: ldap:ds.example.com:ou=auto.home,dc=example,dc=com
What these entry is doing is it will inform autofs where to get the mount information for /home
For the auto.home we need to create another ou.
dn: ou=auto.home,dc=example,dc=com
ou: auto.home
objectClass: top
objectClass: organizationalUnit
objectClass: automountmap
Under this ou we will have our entries for each user. Our user should look like the following
dn: cn=tux,ou=auto.home,dc=example,dc=com
cn: tux
objectClass: automount
automountInformation: -rsize=8192,wsize=8192,intr NfsServer.example.com:/home/tux
The automountInformation is telling the autofs the options to use when it mounts the directory, and what server to get the directory from.
The last thing you will need to do is edit the /etc/sysconfig/autofs file and enable the following lines.
#
# Other common LDAP nameing
#
DEFAULT_MAP_OBJECT_CLASS="automountMap"
DEFAULT_ENTRY_OBJECT_CLASS="automount"
DEFAULT_MAP_ATTRIBUTE="ou"
DEFAULT_ENTRY_ATTRIBUTE="cn"
DEFAULT_VALUE_ATTRIBUTE="automountInformation"
Once you have made the changes and saved the file restart autofs
[root@remote_system ~]# service autofs restart
You should now be able to su - tux and see that his home directory has been mounted. If not check the /var/log/messages. You can also turn up the debug in the /etc/sysconfig/autofs file.
If you want all users to be able to mount their home directory, but don’t want to add an entry for each user, you will take the following.
dn: cn=tux,ou=auto.home,dc=example,dc=com
cn: tux
objectClass: automount
automountInformation: -rsize=8192,wsize=8192,intr NfsServer.example.com:/home/tux
and make it look like
dn: cn=/,ou=auto.home,dc=example,dc=com
cn: /
objectClass: automount
automountInformation: -rsize=8192,wsize=8192,intr NfsServer.example.com:/home/&
Then anyone that has a home directory the server on your NfsServer the autofs will mount it.
Watch for info on how to make auto.misc, and others.
I used the following sites for information on how to do this. http://efod.se/blog/archive/2006/06/27/autofs-and-ldap http://www.linuxjournal.com/article/6266 http://forums.fedoraforum.org/showthread.php?t=138992 http://forums.fedoraforum.org/forum/showthread.php?t=135635&highlight=autofs+ldap
