I dug the below out from the archive.  Is there anything new on the subject?

I've seemed to have slammed head first into the subject.  Got SUSE and RHEL 3 using nisObjects happily (apparently they'll support either model).  Just configured a Solaris 10 box as a client and it wants automountMap.  Even worse, Solaris 9 and 10 do automountMap, Solaris 8 does nisObjects.  Fortunately, I have all three versions running.  (Info on Solaris' automount: http://www.informit.com/articles/article.asp?p=31550&seqNum=4&rl=1 )

I tried loading the 10rfc2307bis.ldif (by replacing the 10rfc2307.ldif file) and slapd wouldn't restart. 

Any idea to a) get the automountMap objects in the schema?  b) possibly support both models?

There has been a lot of confusion around this issue (mostly on my part). I think one of the problems is that rfc2307 support from OS vendors is now deprecated in favor of rfc2307bis http://www.ietf.org/internet-drafts/draft-howard-rfc2307bis-01.txt, which is still in Internet Draft phase (and is due to expire very quickly). A new draft is being worked on with the goal of generating a new RFC. The bis draft has one problem with it, in that it requires the use of the authPassword attribute (defined in RFC 3112 http://www.ietf.org/rfc/rfc3112.txt). FDS does not support this (and neither does OpenLDAP AFAICT). I have attached a file called 10rfc2307bis.ldif. This is the schema from the 2307bis I-D in FDS schema format.

The preferred way to map the automount information is to use the automount attributes and objectclasses in the RFC 2307bis draft schema. The problem is that I don't know all of the vendor support. So far I've been unable to find out what RHEL3 and RHEL4 support. I've been told that Solaris has support for the bis schema.

If you like, you can replace the 10rfc2307.ldif schema supplied with FDS with the attached file, and see what happens.
