Directory Sync
Directory Sync allows you to sync people and group data from an external LDAP directory into the Domino® directory. Currently data from Active Directory can be synced.
Directory Sync makes it easy for your HCL Domino® users to address mail to and see details about users in your organization who do not use Notes® such as Microsoft™ Outlook users registered in Active Directory. With this feature, Active Directory users automatically have Person documents in the Domino® directory so that Notes® users can find their addresses and other information. Without Dirsync, Notes® users must know the addresses of the Active Directory users before they can send mail to them, unless Person documents are added for them manually.
