Automount Maps

In order to use the automount information stored in your directory, you must shift your focus to the automount daemon itself, specifically Linux’s kernel-based autofs. As it currently stands, autofs (v3.1.7 and the 4.0 preview releases) supports the undocumented automount and automountMap object classes. However, Red Hat has updated the package in its distribution (autofs-3.1.7-28) to look up mount points based on the nisObject and nisMap classes described in RFC 2307 (and included in nis.schema). The LDAPbis workgroup’s revisions to RFC 2307 will include new schema items for storing automount information, but for the moment, nisObject and nisMap have the largest support base from Red Hat, Sun, and PADL. Figure 6-8 shows the required and optional attributes for these two new object classes.

Tip

Red Hat’s automount patches can be obtained from either http://people.redhat.com/nalin/autofs/ or in the latest autofs SRPM at ftp://ftp.redhat.com/pub/redhat/linux/rawhide/SRPMS/SRPMS/.

PADL’s migration tools include a script (migrate_automount.pl ) for converting an automount map to LDIF. Here, you will convert a single automount point in /opt to a directory entry. You can see from the /etc/auto.opt excerpt that the LDIF entry contains all of the information needed for mounting /opt/src. This time, PADL’s script does create ...
