Yes, actually it's /home/projects ...

Automount maps have nothing to do with machine entries in LDAP, but each
automount entry would need an LDAP entry:
$ ldapsearch -x "(objectclass=automountmap)" -LLL
dn: ou=auto.cae,ou=Mounts,dc=cae,dc=co,dc=za
objectClass: top
objectClass: automountMap
ou: auto.cae
dn: ou=auto.master,ou=Mounts,dc=cae,dc=co,dc=za
objectClass: top
objectClass: automountMap
ou: auto.master
$ ldapsearch -x "(objectclass=automount)" -LLL
dn: cn=users, ou=auto.cae,ou=Mounts,dc=cae,dc=co,dc=za
objectClass: automount
automountInformation: -rw,hard,nosuid,rsize=8192,wsize=8192
hercules:/home/users

As you will see, the only entries in our LDAP automount maps are those we
need all the time (/home/{users,groups,projects}) on most machines (the
ones people need to be sure of, so we can modify the LDAP automount
entries and be sure each machine will use the correct share on next
access), I have done no configuration on /net and /misc (just using the
default auto.master, auto.net, auto.misc - LDAP stuff is picked up
automagically without *any* configuration besides that done during
installation for LDAP auth).
I can browse any machine our firewall will let me use NFS/portmap to ...
We aren't a "big unix shop" (we have more Windows boxen), but I still
haven't seen anything am-utils can do that autofs can't.
