What Is User Conversion
What Is User Conversion?

Windows NT Server enables you to use domains and trust relationships to centralize administration. With a trust relationship, servers in one domain recognize and allow access to accounts from another domain. If you design your network with domains and trust relationships in mind, you need to create only one account for each user, and that account can be used to give the user access to network resources.

To help you implement a trusted domain model, the Microsoft Windows NT User Conversion tool maps LAN Manager user accounts and groups into Windows NT Server domains. User Conversion provides:

Automatic mapping between LAN Manager and Windows NT Server user accounts and groups that have identical names.

This allows User Conversion to automatically identify and merge user accounts and groups when the old LAN Manager name is identical to the new Windows NT Server name.

Manual mapping between LAN Manager and Windows NT user accounts and groups that do not have identical names.

This allows you to select and merge user accounts and groups that are not identically named.  This is particularly useful when a user has several LAN Manager user accounts, under various user names, that should be combined into a new, single user account on the Windows NT Server computer.

Manual mapping of LAN Manager groups to new Windows NT Server local groups.

Each new local group will consist of the same users that were in the old LAN Manager group, except that the member user accounts will have been mapped to a Windows NT Server domain.

You can run User Conversion on its own, or from within Windows NT Server Upgrade Manager.  In Windows NT Server Upgrade Manager, User Conversion corresponds to the Map To Trusted Domain Accounts tool.

User Conversion Prerequisites

In order for User Conversion to map user accounts from LAN Manager to Windows NT Server, the needed Windows NT Server accounts must already exist in a local or in a trusted domain. You cannot use User Conversion to create new user accounts. (This does not restrict the ability to combine multiple LAN Manager domains into a single Windows NT Server domain.)

User Conversion requires a NETACC.BKP file, which contains information about the user accounts and groups that will be mapped to the Windows NT Server computer.  A NETACC.BKP file is created when the backacc utility is run on a LAN Manager server in the first phase of the upgrade.

User Conversion can be used to map users only during the upgrade process.  Once the upgrade is complete and your domain is put into production on your network, you cannot map any additional users from that upgraded domain.  This restriction is required because the organization of files and directories on the disk partitions on the Windows NT Server computer will most likely change as users add, modify, and delete files. Once the file organization changes, the snapshot of the file permissions that existed under LAN Manager is no longer valid, and the file permissions can no longer be restored correctly. However, you will still be able to map users from other trusted domains as they are upgraded.

Selecting a NETACC.BKP File


File Name

The File Name box displays the name of the file that will be opened and loaded into User Conversion. The name of this file is NETACC.BKP.

Note:	There may be multiple NETACC.BKP files stored in multiple locations. You should select the appropriate NETACC.BKP file by using the Networks button, the Directories box, and the Drives box.


List Files Of Type

The List Files Of Type box determines the types of files that will be listed. The default (*.*) is to list all files.


Directories

If the displayed directory path is not the storage location of the NETACC.BKP file you want to open, select a different path in the Directories box.


Drives

If the displayed disk drive is not the storage location of the NETACC.BKP file you want to open, select a different drive from the list in the Drives box.


Network Button

Use the Network button to establish a connection to a shared network directory.


The User Conversion Dialog Box

Use the User Conversion dialog box to map and convert LAN Manager user accounts and groups to Windows NT Server user accounts and groups.

Choose one of the following buttons for information about the dialog box:

 LAN Manager Accounts List

 Trusted Domain Box

 Trusted Accounts List

 Current Assignments List

 Auto Map Button

 Manual Map Button

 Convert Button

 Add Group Button

Mapping User Accounts and Groups


LAN Manager Accounts Llist

This box lists the user accounts and groups from the NETACC.BKP file. One or more names can be selected from the list.

Note:	Once a user account or group has been mapped, it is removed from this list, and it appears in the Current Assignments list.


Trusted Domain Box

This box displays the selected domain.

When this list box is opened, it lists the local domain and all domains trusted by the local domain.


Trusted Accounts List

This box lists the user accounts and global groups of the domain that is displayed in the Trusted Domains box. (If the local domain is selected, its local groups are also listed.)


Current Assignments List

This box lists the mapped user accounts and groups. The LAN Manager names are shown in the left column. The Windows NT names (including domain) are shown in the right column.

These are the mappings that will be performed when the convert button is chosen.


Auto Map Button

This button allows you to merge identically-named user accounts, and identically-named groups.

When one or more names are selected from the LAN Manager Accounts list and this button is chosen, User Conversion examines the Trusted Accounts list for identical names. When a match is found, a mapping is added to the Current Assignments list, and that name is removed from the LAN Manager Accounts list. When no match is found, that name remains listed in LAN Manager Accounts.

Note:	User accounts will be mapped only to user accounts, and groups will be mapped only to groups. Even if they have identical names, groups are not mapped to user accounts, nor are user accounts mapped to groups.


Manual Map Button

This button allows you to merge user accounts and groups when they are not identically named. This is particularly useful when a user had several LAN Manager accounts under various usernames, but will be provided with only one Windows NT account.

When one or more names are selected from the LAN Manager Accounts list, and when one name is selected from the Trusted Accounts list, choosing this button adds those mappings to the Current Assignments list and removes the selected names from the LAN Manager Accounts list.

Note:	User accounts can be mapped only to user accounts, and groups can be mapped only to groups.


Convert Button

This button performs the conversions as mapped in the Current Assignments list, and then exits User Conversion.


Add Group Button

When a group is selected from the LAN Manager Accounts list, choosing the button adds a new local group of the same name to the Current Assignments list, maps the selected LAN Manager group to that new local  group, and adds the member user accounts from the LAN Manager group to the new group.

Note:	This can only be performed for the local domain. It cannot be done for trusted domains. Also, a local group with the same name cannot already exist in the Windows NT Server domain.


Sort By

The Sort By option determines how the Current Assignments list is sorted.

If you choose User Name, the Current Assignments list is sorted by the old LAN Manager account names.

If you choose Domain, the Current Assignments list is sorted first by the Windows NT domain names (the right column) and then, for each domain, by the old LAN Manager account names (the left column).


Remove Button

When one or more accounts are selected from the Current Assignments list, choosing the Remove button removes the selected mappings. The removed LAN Manager accounts return to the LAN Manager Accounts list.


Starting User Conversion

There are two ways to run User Conversion: from within Windows NT Server Upgrade Manager or independently. Running from within Windows NT Server Upgrade Manager is recommended.

To run User Conversion from within Windows NT Server Upgrade Manager

When configuring Upgrade Manager, include the Map To Trusted Domain Accounts tool in the Upgrade Tool Schedule.

When Upgrade Manager executes this tool, the User Conversion program starts, and the Open dialog box appears.

To run User Conversion independently

1.	From the command prompt, change to the UPGRADE directory.

2.	Type userconv.

Optionally, you can append the /codepage:codepagenumber switch, which specifies the code page to be used by the upgrade utility.  This switch is required only when changing languages as part of the upgrade.  The codepagenumber is a 3-digit decimal number indicating the code page that was used by the LAN Manager for OS/2 server. This number is listed in the upgrade file ADVISORY.TXT.

The User Conversion program starts, and the Open dialog box appears.

Selecting a NETACC.BKP File

Once User conversion starts, the Open dialog box appears.  In this dialog box you specify the NETACC.BKP file whose user accounts and groups will be mapped to Windows NT.

To select a NETACC.BKP file for mapping to Windows NT Server

1.	In the File Name box, select a NETACC.BKP file.

Often, this file is located in the local UPGRADE directory and is automatically selected in the File Name box.  However, if necessary you can use the Network button, the Drives box, and the Directories box to locate the appropriate NETACC.BKP file.

Note:	The information in each NETACC.BKP file can be mapped and converted only once by the User Conversion program.  Do not select a NETACC.BKP file that has previously been mapped and converted.

2.	Choose the OK button.

That NETACC.BKP file is loaded, and the User Conversion dialog box appears.

Mapping User Accounts and Groups

User Conversion maps and converts LAN Manager user accounts and groups to Windows NT Server user accounts and groups.

To map user accounts and groups

1.	Start User Conversion.

2.	Select the appropriate NETACC.BKP file.

3.	Select a domain in the Trusted Domain box.

4.	To merge identically named user accounts and groups, select one or more names from the LAN Manager Accounts list, and then choose the Auto Map button.

User Conversion searches in the Trusted Accounts list for identical names.  When it locates a match, a mapping from the LAN Manager name to the identical Windows NT name is added to the Current Assignments list, and the mapped LAN Manager name is removed from the LAN Manager Accounts list.  When no match can be found, the LAN Manager name remains in the LAN Manager Accounts list.

Note:	User accounts are mapped only to user accounts, and groups are mapped only to groups.  Even if they have identical names, groups are not mapped to user accounts, nor are user accounts mapped to groups.

5.	When user accounts or groups do not have identical names, you can manually merge them.  Select one or more names from the LAN Manager Accounts list, select one name from the Trusted Accounts list, and then choose the Manual Map button.

Each selected LAN Manager name is mapped to the selected Windows NT name.  The mappings are added to the Current Assignments list, and the mapped LAN Manager names are removed from the LAN Manager Accounts list.

Note:	User accounts can be mapped only to user accounts, and groups can only be mapped to groups.

6.	To map a LAN Manager group to a new Windows NT local group, select a group from the LAN Manager Accounts list, and then choose the Add Group button.

A new local group of the same name is added to the Current Assignments list and the selected LAN Manager group is mapped to that new local group. Also, the mapped LAN Manager group is removed from the LAN Manager Accounts list and the member user accounts from the LAN Manager group are added to the new group.

Note:	This can only be performed for the local domain.  It cannot be done for trusted domains.

7.	To map LAN Manager user accounts and groups into other Windows NT Server domains, repeat steps 3-6.

You can choose to map to the local domain, or to a domain that trusts the local domain.

8.	To perform the conversion as mapped in the Current Assignments list, choose the Convert button.

The conversion will be performed, and then User Conversion will quit.

User Conversion will verify that the user names of accounts being mapped exist only once on the network.  If any user is left unmapped, User Conversion will create an output file containing the account information for each unmapped user. User Conversion will generate error messages as a result of account name conflicts.
