The LotusScript NotesRegistration class provides a way to register new users. The RegisterNewUser method in the class, in addition to properties within the class, are used to accomplish the registration. The RegisterNewUser method can create an ID file for the new user, create a mail file, and add a Person Document to the Domino Directory.

The syntax of the RegisterNewUser method is as follows (see Supporting Information below for additional details):

notesRegistration.RegisterNewUser( lastname$, idfile$, mailserver$ [, firstname$ [, middle$ [, certpw$ [, location$ [, comment$ [, maildbpath$ [, fwddomain$ [, userpw$ [, usertype% [, altname [, altnamelang ]]]]]]]]]]] )

NOTE: The MailServer$ parameter must be passed in full canonical format (such as CN=ServerA/OU=West/O=Widgets). If you attempt to send mail to users who were registered without the MailServer in canonical format, the following error can occur: "No route found to server X/Org from server X/Org: check server and connection documents in Name and Address Book."

The following properties in the NotesRegistration class must be set prior to calling the RegisterNewUser method:

RegistrationServer
CertifierIDFile
IDType
MinPasswordLength

NOTE: Details on each property can be found in the Domino Designer Online Help.

The following sample LotusScript code demonstrates how to use the method. Replace the text in brackets <> with the information specific to your environment. It could potentially be adapted to loop through an array or text file for batch processing.

Dim Session As New NotesSession
Dim db As NotesDatabase
Dim NR As New NotesRegistration
Dim UseridFile As String
Dim Lname As String
Dim Fname As String
Dim MailServer As String
Dim Mlocation As String
Dim UserPassword As String
Dim UserMailPath As String
Dim CertPassword As String
Dim Comment As String
NR.StoreIDinAddressBook = True  
NR.CreateMailDB = True
NR.UpdateAddressBook = True
NR.IDType = ID_HIERARCHICAL

'PARAMETERS TO CODE:
NR.Expiration = Now() + (365 * 2)
NR.registrationServer="NotesServer"
NR.certifieridfile = ""
NR.OrgUnit = ""
MailServer = "" 'Must use full canonical version of name.  
FName = ""
MName = ""
LName = ""
UserPassword = ""
UserIDFile = "" 'May also use:  =Trim(Left(FName,1)+LName)
UserMailPath = "\" * useridfile
Mlocation = ""
Comment = "This entry added via agent on date x/y/z"  'As desired
CertPassword =    

If NR.RegisterNewUser(LName, UserIDFile, MailServer, FName, Mname , CertPassword, MLocation, Comment, UserMailPath, , UserPassword) Then
Msgbox("User was Registered Successfully")
Else
Msgbox("Sorry, User was Not Registered, Please try again")
End If
