<title>Managing Passwords</title>

<primary>Passwords</primary>

</indexterm>

<para>OpenIDM provides password management features that help you enforce

password policies, limit the number of passwords users must remember, and

let users reset and change their passwords.</para>

<section xml:id="enforce-password-policy">

<title>Enforcing Password Policy</title>

<para>A password policy is a set of rules defining what sequence of

characters constitutes an acceptable password. Acceptable passwords generally

are too complex for users or automated programs to generate or guess.</para>

<para>Password policies set requirements for password length, character sets

that passwords must contain, dictionary words and other values that passwords

must not contain. Password policies also require that users not reuse old

passwords, and that users change their passwords on a regular basis.</para>

<indexterm>

<primary>Objects</primary>

<secondary>Managed objects</secondary>

<tertiary>Passwords</tertiary>

</indexterm>

<para>OpenIDM enforces password policy rules as part of the general policy

service. For more information about the policy service, see

<link xlink:href="integrators-guide#chap-policies"

xlink:role="http://docbook.org/xlink/role/olink">

<citetitle>Using Policies to Validate Data</citetitle></link>. The default

password policy applies the following rules to passwords as they are created

and updated:</para>

<itemizedlist>

<listitem><para>A password property is required for any user object.</para>

</listitem>

<listitem><para>The value of a password cannot be empty.</para></listitem>

<listitem><para>The password must include at least one capital letter.

</para></listitem>

<listitem><para>The password must include at least one number.</para>

</listitem>

<listitem><para>The minimum length of a password is 8 characters.</para>

</listitem>

<listitem><para>The password cannot contain the user name, given name, or

family name.</para></listitem>

</itemizedlist>

<para>You can remove these validation requirements, or include additional

requirements, by configuring the policy for passwords. For more information,

see <link xlink:href="integrators-guide#configuring-default-policy"

<variablelist>

<para>The password validation mechanism can apply in many situations.</para>

<varlistentry>

<term>Password change and password reset</term>

<listitem>

<para>Password change involves changing a user or account password

in accordance with password policy. Password reset involves setting a

new user or account password on behalf of a user.</para>

<para>By default, OpenIDM controls password values as they are

provisioned.</para>

<para>To change the default administrative user password,

<literal>openidm-admin</literal>, see the procedure, <link

<term>Password recovery</term>

<listitem>

<para>Password recovery involves recovering a password or setting a new

password when the password has been forgotten.</para>

<para>OpenIDM provides a self-service end user interface for password

changes, password recovery, and password reset. For more information, see

<section xml:id="password-sync">

<title>Password Synchronization</title>

<indexterm>

<primary>Synchronization</primary>

<secondary>Passwords</secondary>

</indexterm>

<para>Password synchronization intercepts user password changes, and ensures

uniform password changes across resources that store the password. Following

password synchronization, the user authenticates using the same password on

each resource. No centralized directory or authentication server is required

for performing authentication. Password synchronization reduces the number of

passwords users need to remember, so they can use fewer, stronger

passwords.</para>

<para>OpenIDM can propagate passwords to the resources storing a user's

password. OpenIDM can intercept and synchronize passwords changed natively

on OpenDJ and Active Directory. See the example in

<filename>samples/misc/managed.json</filename> where you installed OpenIDM

for a sample password synchronization configuration.</para>

<para>Before using the sample, you must set up OpenDJ and Active Directory,

and adjust the password attributes, set in the sample as

<literal>ldapPassword</literal> for OpenDJ, <literal>adPassword</literal>

for Active Directory, and <literal>password</literal> for the internal

OpenIDM password. Also, either set up password policy enforcement on OpenDJ

or Active Directory rather than OpenIDM, or ensure that all password policies

enforced are identical to prevent password updates on one resource from being

rejected by OpenIDM or by another resource.</para>

<para>Also set up password synchronization plugins for OpenDJ and for Active

Directory. The password synchronization plugins help by intercepting password

changes on the resource before the passwords are stored in encrypted

form. The plugins then send intercepted password values to OpenIDM over an

encrypted channel.</para>
