LDAP-UX Client Services B.05.00 Administrator's Guide

2.5.3 Enabling AutoFS support
AutoFS is a client-side service that automatically mounts appropriate file systems when users
request access to them. If an automounted file system has been idle for a period of time, AutoFS
unmounts it. AutoFS uses name services such as files, NIS, or NIS+ to store and manage AutoFS
maps.
LDAP-UX Client Services supports the automount service under the AutoFS subsystem. This
feature allows users to store AutoFS maps in an LDAP directory server.
2.5.3.1 Automount schemas
This section describes the following automount schemas:
• new automount schema
An automount schema is based on RFC 2307-bis. This schema defines new automountMap
and automount structures to represent the AutoFS maps and their entries in the LDAP
directory.
• nisObject automount schema
The nisObject automount schema definesnisMap and nisObject structures to represent
the AutoFS maps and their entries in the LDAP directory. There are some limitations that
you need to be aware of when using the nisObject automount schema.
The LDAP-UX Client Services supports the new automount schema. The nisObject automount
schema can also be used if configured via attribute mappings. The autosetup program installs
the correct schema. No adjustments are necessary.
Read subsequent subsections of this chapter for the detailed information about the automount
schemas.
2.5.3.1.1 New automount schema
This schema is a new schema defined in RFC 2307-bis. This schema defines new automountMap
and automount structures to represent AutoFS maps and their entries in the LDAP directory.
AutoFS maps are stored in the LDAP directory server using structures defined by this schema.
The RFC 2307-bis automount schema is included with HP-UX Directory Server by default. If you
are installing LDAP-UX with a different directory server, the setup program will import the
new automount schema into your directory server. If you previously configured LDAP-UX
B.03.30 or an earlier version, and are now updating the product to version B.04.00 or later, you
must re-run the setup program to import the new automount schema into the LDAP directory.
The subsequent client systems do not need to re-run the setup program.
2.5.3.1.1.1 Schema
The following shows the RFC 2307-bis automount schema in the LDIF format:
objectClasses: ( 1.3.6.1.1.1.2.16
NAME 'automountMap'
DESC 'Automount Map information'
SUP top STRUCTURAL
MUST automountMapName
MAY description
X-ORIGIN 'user defined' )
objectClasses: ( 1.3.6.1.1.1.2.17
NAME 'automount'
DESC 'Automount information'
SUP top STRUCTURAL
MUST ( automountKey $ automountInformation )
MAY description
X-ORIGIN 'user defined' )
