If you are using https for Open-AudIT, you will need to manually edit the files /usr/local/omk/bin/open-audit_tasks.[sh|vbs]. You will need to update the URL to reflect the https prefix. To use https, there is a line below that should be uncommented, and the regular line commented out. that's all there is to it.
Default regular line
curl -s -o /dev/null --data "" "http://localhost/omk/open-audit/tasks/execute" >/dev/null 2>&1
Commented out line
# curl -s -o /dev/null --insecure --data "" "https://localhost/omk/open-audit/tasks/execute" >/dev/null 2>&1
The config option oae_server located in /usr/local/omk/conf/opCommon.nmis under the openauditenterprise section will also need to be changed. The default value for this is http://127.0.0.1/open-audit/ and changing this to https://127.0.0.1/open-audit/ will allow use of https.
You will also need to be sure the default network address is set to reflect HTTPS in the GUI. To do this navigate to menu -> Admin -> Community -> All Configuration then edit default_network_address to use https ex. https://YOURSERVER/open-audit/
