You can run the server in any of the following security modes:

• OFF, in which access to data sources and the Web Console is unrestricted. Users do not need to provide a password.
• OPSYS, in which the server runs as a Windows service. Requires users to provide their operating system user IDs and passwords when logging on to the server. Each connecting user credentials are authenticated using Microsoft Windows Security Services. The server invokes authentication and impersonation services and controls database access.
• PTH, in which access to the Web Console is controlled by authentication against the user list defined at the configuration level.
• DBMS, in which access to data sources and the Web Console is controlled by authentication against the database list of user IDs. Control of data resources can be accomplished by creating different profiles.
• LDAP, in which access to data resources and the Web Console is controlled by authentication through the established directory.

Some security modes need to be configured before you can activate them. You can see a full description of all server security modes in the Web Console Help, and also in the Server Administration for UNIX, Windows, OpenVMS, IBM i, and z/OS manual. To see it in the Web Console:

1. From the Web Console menu bar, select Help, then Contents and Search.

   The Web Console Help window opens.

2. In the left pane, expand Server Administration.
