+Automount

+RFC 2707bis http://www.padl.com/~lukeh/rfc2307bis.txt
+
+A few notes on automount:
+- It was a design decision to not support different maps by location
+- The default parent when adding an indirect map is auto.master
+- This uses the short format for automount maps instead of the
+  URL format. Support for ldap as a map source in nsswitch.conf was added
+  in autofs version 4.1.3-197.  Any version prior to that is not expected
+  to work.
+
+As an example, the following automount files:
+
+auto.master:
+/-	auto.direct
+/mnt	auto.mnt
+
+auto.mnt:
+stuff -ro,soft,rsize=8192,wsize=8192 nfs.example.com:/vol/archive/stuff
+
+are equivalent to the following LDAP entries:
+
+# auto.master, automount, example.com
+dn: automountmapname=auto.master,cn=automount,dc=example,dc=com
+objectClass: automountMap
+objectClass: top
+automountMapName: auto.master
+
+# auto.direct, automount, example.com
+dn: automountmapname=auto.direct,cn=automount,dc=example,dc=com
+objectClass: automountMap
+objectClass: top
+automountMapName: auto.direct
+
+# /-, auto.master, automount, example.com
+dn: automountkey=/-,automountmapname=auto.master,cn=automount,dc=example,dc=co
+ m
+objectClass: automount
+objectClass: top
+automountKey: /-
+automountInformation: auto.direct
+
+# auto.mnt, automount, example.com
+dn: automountmapname=auto.mnt,cn=automount,dc=example,dc=com
+objectClass: automountMap
+objectClass: top
+automountMapName: auto.mnt
