I want to have a Google Search Appliance crawling my file server ressources based on a Netware 6.5 cluster. For checking the users permissions against the hit list entries it is essential the GSA can make a HEAD request to the file. I tried that via the webserver provided by PORTAL.NLM but when sending the request (e.g. via curl) I get "HTTP/1.1 405 Method Not Allowed" back from the HTTP stack. Now I'm looking for a possibility to check the permissions via HTTP but without success.

Is there a parameter I can change to allow HEAD requests?
Please let me know if you have any ideas about this issue.

Best regards
