The Solaris LDAP naming service stores password information and shadow information in the ou=people container of the LDAP directory tree. On the Solaris LDAP naming service client, you can use the passwd -r ldap command to change a user's password. The LDAP naming service stores the password in the LDAP repository.
Password policy is enforced on the Sun Java System Directory Server. Specifically, the client's pam_ldap module follows the password policy controls that are enforced on the Sun Java System Directory Server.
