Set trace for ISAM SPNEGO issues

Enable trace for SPNEGO to retrieve more details about WebSEAL issues.

When directed by IBM Support, collect the SPNEGO diagnostic data when WebSEAL does not start.

Steps

  1. Log in to the local management interface.

  2. Select Secure Web Settings > Manage > Reverse Proxy.

  3. Select the reverse proxy.

  4. Select Manage > Configuration > Edit Tracing Configuration File.

  5. Add an entry to the file. Example entry that directs output to the spnegotrace.log file: 
    bst:*.9:TEXTFILE:spnegotrace.log

  6. Turn on per-process trace to diagnose WebSEAL start issues:

    1. Uncomment the last line by removing the # symbol. 
      #Route to a per-process text file
*:*.9:TEXTFILE.10.1000:trace.log

    2. Stop and restart WebSEAL.

    3. Check the output in trace.log. If you start WebSEAL with the pdweb_start command, there are two traces with different pids.
