Duplicated Logins Scanner for NDS/eDirectory will come handy for network administrators who implement the Novell NIMS/NetMail mail system. This system requires unique login names for every user who works with it. If you install NetMail to the well-developed NDS tree with a large number of containers and users, the search for duplicated logins could be big trouble.

The scanner can do the following:

1. Full scan of an NDS tree beginning from specified context ([Root] by default). This operation is long enough. Running time depends on computer where the scanner is run and the general network performance. Full scan of a medium-sized tree with approximately 200 organizational units, 2,500 users and 10,000 objects takes 5 seconds on PIV-2400 workstations. When scan is finished the full report is generated. This scanner capability is useful when you prepare your network for the first installation of the NetMail server or simply want to find all duplicates.

• Scan a tree for the specified login. You may do the full scan of the selected (sub)tree (it reveals all instances of the given login; such a scan requires the same time as a full subtree scan) or you may do the "quick" scan which reveals only the first occurrence of the given login (search time is unpredictable). This scanner capability allows you to quickly find out if the specified login already exists to prevent creation of a duplicated login name. The time of the search is a little longer than in NWAdmin32, but the quicker start of the scanner and the usability of the application's interface make up for it.
