  Working with LDAP Queries
How to set up Microsoft Exchange 2000 server to allow “anonymous bind.”
How to set up AsyncOS to retrieve LDAP data from a Microsoft Exchange 2000 server using both 
“anonymous bind” and “anonymous” authentication.
Specific permissions must be made to a Microsoft Exchange 2000 server in order to allow “anonymous” 
or “anonymous bind” authentication for the purpose of querying user email addresses. This can be very 
useful when an LDAP query is used to determine the validity of an income email message to the SMTP 
gateway.
Anonymous Authentication Setup
The following setup instructions allow you to make specific data available to unauthenticated queries of 
Active Directory and Exchange 2000 servers in the Microsoft Windows Active Directory. If you wish to 
allow “anonymous bind” to the Active Directory, see 
Procedure 
Step 1
Determine required Active Directory permissions.
Using the ADSI Edit snap-in or the LDP utility, you must modify the permissions to the attributes 
of the following Active Directory objects:
The root of the domain naming context for the domain against which you want to make queries.
All OU and CN objects that contain users against which you wish to query email information.
The following table shows the required permissions to be applied to all of the needed containers.
Step 2
Set Active Directory Permissions
Open ADSIEdit form the Windows 2000 Support Tools.
Locate the Domain Naming Context folder. This folder has the LDAP path of your domain.
Right click the Domain Naming Context folder, and then click Properties.
Click Security.
Click Advanced.
Click Add.
Click the User Object Everyone, and then click OK.
Click the Permission Type tab.
Click Inheritance from the Apply onto box.
Click to select the Allow check box for the Permission permission.
