Ok, for clarification, this is why I'm proposing having the 
location/name/whatever in the DN.

You have to supply a base search DN in the autofs config file, on Linux 
anyway.

So if we cleverly supply this baseDN it is easy to support multiple 
configurations.

autofs searches for its base configuration like this:

SRCH base="dc=example,dc=com" scope=2 
filter="(&(objectClass=automountMap)(automountMapName=auto.master))" 
attrs="automountMapName"

So if we can set that base to something where a unique auto.master will 
be found we can control what is in that master. It seems like that is 
the only thing that truly needs to be unique.
