This JavaScript will check if an exact match is found in the Domino Directory. If no match is found, an alert message will appear and return focus to the field.

The function takes four parameters, which are explained in the source code. The exact match in the Domino directory is case insensitive. The main goal is to make sure the name is able to be resolved in the Domino directory.

If you omit the myOrg argument to the isInNab function, the common name will be searched instead of the canonical name. However, the name will only be matched up to the number of characters you enter. A mail routing failure may occur if duplicate are names found. For my purposes, I am at least sending the organization to the function. Passing the organization will place distinct delimiters around the name to get the exact match. ("CN=" is the prefix and "O=/..." is the suffix)

/*
Below is a JavaScript code snippet that 
may be added to the onBlur event 
of a text field to validate against the 
Domino directory.
*/

var myHost = window.location.protocol +
 "//" + window.location.host + "/names.nsf"; 
var myOrg = "Sandbox"; 
var alertmsg = "Name not found in Addressbook. 
Please try again."; isInNab( this, myHost, myOrg, alertmsg );


/*
Below is the code that may be added to the JSHeader of the form 
that contains the field that is being validated.
*/

// Checks a single public address book to 
confirm if a name is found.
/*
This function is intended for IE browsers 
that provide the Microsoft.XMLDOM

fld   = The web text field that contains the SendTo name.
nabDB = The URL that points to the Domino directory. 
Example: http://mydomain.com/names.nsf
myOrg  = The organization name used in the
 Domino hierarchy. If you pass an empty myOrg
                   value, the comman name will be 
searched in the ($Users) view if the Domino Directory.
                   You can also send an ORG/OU, ORG/OU/OU..., etc 
as an aurgument.
alertMsg = The message that appears to the 
user if the name is not found in the Domino Directory.                   
*/                  

function isInNab ( fld, nabDB, myOrg, alertMsg ) { 

 if ( ! alertMsg ) {
  alertMsg = "Name not found in public address book.";
 }
 
 myOrg = myOrg.toLowerCase();

same as the HTML page that calls the URL.
