A workaround to fix this issue is to disable the WMIDaemon (WMI authentication) in IWSVA by following the steps below:

1. SSH into IWSVA as root
2. Enter enable mode using the command below
# su enable

3. Enter the following command to disable the WMI module
enable # configure module ldap trans_auth disable

4. Exit enable mode
# exit

5. Monitor the LDAP server.

Note: This will not affect IWSVA authentication because this is a secondary daemon. The main Authentication daemon will still be able to query the LDAP server. This procedure will leave IWSVA unavailable for 5 to 10 minutes so plan accordingly.
