Info

Note – You need to consider the following configuration issues when setting thepasswordStorageScheme attribute. If a NIS, NIS+, or another client usingpam_unix is using LDAP as a repository, then passwordStorageScheme needs tobe crypt. Also, if using pam_ldap with sasl/digest-MD5 with Sun Java SystemDirectory Server, passwordStorageScheme must be set to clear.Account ManagementLDAP naming services take advantage of the password and account lockout policysupport in Sun Java System Directory Server. You can configure pam_ldap(5) tosupport user account management. passwd(1) enforces password syntax rules set bythe Sun Java System Directory Server password policy, when used with the properPAM configuration.The following account management features are supported through pam_ldap(5).These features depend on Sun Java System Directory Server’s password and accountlockout policy configuration. You can enable as many or as few of the features as youwant.■■■■Password aging and expiration notificationUsers must change their passwords according to a schedule. A password expires ifit is not changed within the time configured. An expired password causes userauthentication to fail.Users see a warning message whenever they log in within the expiration warningperiod. The message specifies the number of hours or days until the passwordexpires.Password syntax checkingNew passwords must meet the minimum password length requirements. Inaddition, a password cannot match the value of the uid, cn, sn, ormail attributesin the user’s directory entry.Password in history checkingUsers cannot reuse passwords. If a user attempts to change the password to onethat was previously used, passwd(1) fails. LDAP administrators can configure thenumber of passwords kept in the server’s history list.User account lockoutA user account can be locked out after a given number of repeated authenticationfailures. A user can also be locked out if his account is inactivated by anadministrator. Authentication will continue to fail until the account lockout time ispassed or the administrator reactivates the account.150 System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) • January 2005
Note – The preceding account management features only work with the Sun JavaSystem Directory Server. For information about configuring the password and accountlockout policy on the server, see the “User Account Management” chapter in theAdministration Guide for the version of Sun Java System Directory Server that you areusing. Also see “Example pam_conf file for pam_ldap Configured for AccountManagement” on page 201. Do not enable account management for proxy accounts.Before configuring the password and account lockout policy on Sun Java SystemDirectory Server, make sure all hosts use the “newest” LDAP client with pam_ldapaccount management.In addition, make sure the clients have a properly configured pam.conf(4) file.Otherwise, LDAP naming services will not work when proxy or user passwordsexpire.Note – After you enable pam_ldap account management, all users must provide apassword any time they log in to the system. A login password is required forauthentication. Therefore, nonpassword-based logins using tools such as rsh,rlogin, orssh will fail.Chapter 9 • LDAP Basic Components and Concepts (Overview) 151
