 Hello,
 
 I'm attempting to migrate an existing (and working) nis automount system 
 to ldap. We have several layers of nested maps and I'm attempting to 
 recreate that in LDAP.
 
 # Automount master for /foo
 dn: cn=/foo, ou=auto.master,dc=phy,dc=duke,dc=edu
 objectClass: automount
 cn: /foo
 automountInformation: ldap ldapserver:ou=auto.phy,dc=phy,dc=duke,dc=edu
 
 dn: ou=auto.phy, dc=phy,dc=duke,dc=edu
 objectClass: top
 objectClass: automountMap
 ou: auto.phy
 
 # mounting /foo/web works great!
 dn: cn=web, ou=auto.phy, dc=phy,dc=duke,dc=edu
 objectClass: automount
 cn: web
 automountInformation: -fstype=nfs nfsserver01:/srv/httpd
 
 # here is my attempt at nesting another level
 dn: cn=project, ou=auto.phy,dc=phy,dc=duke,dc=edu
 objectClass: automount
 cn: project
 automountInformation: ldap ldapserver:ou=auto.project,dc=phy,dc=duke,dc=edu

I'm not sure about using this older syntax.
Even if it is correct and we find a bug with it I'd be inclined to
recommend using the newer syntax if possible.

That would be (IIRC):
automountInformation: ldap://ldapserver/ou=auto.project,dc=phy,dc=duke,dc=edu

 
 # This fails. I get automount: failed to mount /foo/project
 dn: ou=auto.project, dc=phy,dc=duke,dc=edu
 objectClass: top
 objectClass: automountMap
 ou: auto.project
 
 # this never shows up (ghosting enabled)
 dn: cn=linux, ou=auto.project, dc=phy,dc=duke,dc=edu
 objectClass: automount
 cn: linux
 automountInformation: -fstype=nfs nfsserver02:/srv/linux
 
 I can't see to find an example of nest ldap maps. I'm using 
 autofs-5.0.5-31.el6 if that makes any difference.

Log a RHEL bug (you probably should go via support actually) and include
a full debug log.

That is set LOGGING=debug in /etc/sysconfig/autofs and ensure that
daemon.* output is being captured by syslog.

 
 Thanks!

 My problem was the lack of -fstype=autofs.

Oh .. yeah, that may well be it, but that should have been needed in the
original map. Maybe a look at a debug log would be useful and that
should show pretty quickly if it is just the missing fstype option.

 
 This works:
 dn: cn=project,ou=auto.phy,dc=phy,dc=duke,dc=edu
 objectClass: automount
 cn: project
 automountInformation: -fstype=autofs ou=auto.project,dc=phy,dc=duke,dc=edu
 
 I also think this is called layering rather than nesting.. but I'm 
 not sure.

Maybe, but the terminology I've always used for these is submount, as
in a sub autofs mount.
