The syntax is the same, but the cn attributes are paths instead of
keys for an automount map. Here's some LDIF:
The helper searches under the base defined in /etc/openldap/ldap.conf
for an object named "ou=auto.master" of type "automountMap", and then
performs a subtree search under that object to get a list of "automount"
objects, which it formats and prints as entries, similar to the way
"ypcat -k" works. (Originally this was done using ldapsearch, but it's
really hard to do base64 conversions in a shell script without help.)

Patching the lookup module to try the nisObject/nisMap method is looking
like a better idea, given that autofs wants to maintain compatibility
with SunOS (except in cases where the map syntax is just too weird). If
I find time today, I'll try to put together a patch that does this.
