Issue/Introduction

This article helps you in resolving the issue when you notice an error "The server is configured for the NTLM authentication method, but the Jespa component is not installed in the WEB-INF/lib directory"

Resolution

This error occurs when the jcifs files required for NTLM authentication to work are missing from the " <spotfire-server installation>/tomcat/webapps/spotfire/WEB-INF/lib" folder.

This jcifs-1.3.19.zip can be downloaded from this link:

​To resolve this issue follow the instructions in the "Downloading third-party components (JCIFS) for NTLM authentication" reference:

  1. Go to http://public.tibco.com/pub/tibco_oss/jcifs/.
  2. Download and extract jcifs_1.3.19.zip to the following directory: <installation directory>\tomcat\webapps\spotfire\WEB-INF\lib.
    The required jcifs.jar file appears in the ...\WEB-INF\lib directory.
  3. Restart the server.
