Authentication Support Features

Authentication support provides a mechanism for performing Windows authentication between a cooperating client and server software. It comprises MCP and Windows components which combine to support NTLM authentication between an MCP server and Windows client or between a Windows server and an MCP client.

These services are used by:

  • Programmer's Workbench

  • Web Transaction Server

  • License Center

  • Workload Center

Other products may also use authentication support.

Installing Authentication Support to the MCP Environment

The AUTHSUPPORT library is installed during normal MCP software installation.

Perform the following steps if you need to manually install the AUTHSUPPORT library:

  1. Copy the new AUTHSUPPORT library from the installation media to the desired family:

    COPY *SYSTEM/AUTHSUPPORT FROM <media> TO <familyname>
  2. Use the SL (Support Library) command to associate the library with the AUTHSUPPORT function name:

    SL AUTHSUPPORT = *SYSTEM/AUTHSUPPORT ON <familyname>

Installing Authentication Support to the Windows Environment

The Authentication Support dll is installed when a Windows client such as Programmer's Workbench is installed. The dll is installed in one of the following folders:

C:\Program Files\Common Files\Unisys\MCP\AuthSupport

or

C:\Program Files (x86)\Common Files\Unisys\MCP\AuthSupport
