User-level security features are not available in databases that use one of the new file formats (.accdb, .accde, .accdc, .accdr).
User-level security is not supported by the new file formats in Microsoft Office Access 2007.
You can continue to manage user-level security in database files that use an earlier Access file format (such as an .mdb or .ade file). We recommend this only if you already have a user-level security solution in place that you want to keep using.
Important: Do not convert your database to one of the new file formats if you want to continue using user-level security. The following procedure works only in databases that use an earlier Access file format, such as .mdb files.
Open the database that has user-level security settings that you want to manage.
On the Database Tools tab, in the Administer group, click Users and Permissions.
Click one of the following commands:
User and Group Permissions Use this to grant or revoke user or group permissions, or to change the owner of database objects.
User and Group Accounts Use this to create or delete a user or a group, to change the password or the group membership of a user, or to change the database Logon password.
User-level Security Wizard Use this to start the Security Wizard, which makes an unsecured backup copy of your database and guides you through the process of implementing user-level security features.
Note: These commands are not available in databases that use one of the new file formats.
Tip: To start the Workgroup Administrator tool, create a macro that has a RunCommand action. Set the Command argument to WorkgroupAdministrator. If the WorkgroupAdministrator argument is not listed, on the Design tab, in the Show/Hide group, click Show All Actions.
Other security features
For better security, consider using one or more of the following features:
Encryption The encryption tool in Office Access 2007 makes your data unreadable by other programs or tools, and it forces users to enter a password to use the database. The encryption tool is available only in databases that use one of the new file formats.
Database server You can store your data on a database server that manages user security, such as Microsoft SQL Server. Then, use Access to build queries, forms, and reports by linking to the data on the server. You can use this technique on a database saved in any Access file format.
Windows SharePoint Services site You can leverage user security and other Windows SharePoint Services features, such as working offline. There are a variety of implementation options, depending on which Windows SharePoint Services product you use. Some Windows SharePoint Services integration features are available only in databases that use one of the new file formats.
New usability features
Several new features can help you manage how users use a database. The Navigation Pane is highly customizable, and several new macro actions can help you control the way that users navigate your database.
