The Lightweight Directory Access Protocol (LDAP) server database is a repository for 
employee directories. These directories include the names of employees along with various 
types of personal data such as a phone number, email address, and other information that is 
exclusive to the individual employee. The LDAP database is composed of objects containing 
attributes and values. Each object name is referred to as a distinguished name (DN). The 
location on the LDAP server where a search begins is called the Base Distinguished Name or 
base DN.
The appliance supports standard LDAP server authentication and Secure LDAP 
authentication. Support for LDAP allows established installations to continue using their 
LDAP server database to authenticate users.
For Secure LDAP, the appliance supports LDAP connections over SSL. The SSL protocol is an 
industry standard for ensuring confidentiality. SSL uses key encryption algorithms along with 
Certificate Authority (CA) signed certificates to provide the LDAP servers a way to verify the 
identity of the appliance.
Note — AsyncOS for Web only supports 7-bit ASCII characters for passwords when using the 
Basic authentication scheme. Basic authentication fails when the password contains 
characters that are not 7-bit ASCII.
Changing Active Directory Passwords
After Active Directory LDAP users change their account passwords, the Active Directory 
LDAP server authenticates them with their current or previous password, depending on the 
Active Directory server configuration. 
If you want users to only be able to authenticate with their new password, you can reboot the 
Active Directory server or, you can wait for the Active Directory server to time out the old 
passwords.
LDAP Authentication Settings
Table 16-12 describes the authentication settings you define when you choose LDAP 
authentication.
