1. Introduction

Autodir offers a simple and effective means to create directories like home directories in a transparent manner.

It relies on the autofs protocol for its operation.

This document explains how to create directories on demand using Autodir in a transparent way to the

applications. This document also explains using transparent backup feature that is possible with Autodir

without bringing system down for backup purpose for all directories managed by Autodir .

1. Introduction

2. Before going to details...

After releasing intraperson beta, I started working on a administration guide that deals with administration

aspects of intraPerson . For more details check http://www.intraperson.com. But I was stuck with one simple

thing. It is easy to create users in ldap −− at least I think so; but how to create home directories for those users

in ldap whereever those ldap accounts are imported?

I found some solutions But I was not satisfied as every solution has serious drawback attached with it. But

after going through autofs documents and hacking little bit, I arrived at conclusion that autofs protocol may

offer much better solution to this challenge.

The result is Autodir , based on the autofs protocol.
