Re: Loaddap and HTTPS

[Arnaud FOREST <Arnaud.Forest@xxxxxxxxxx>]

HI James,

I think I find the problem with my authentification,
Remember I have no trouble with a web browser, but with matlab an error 
occures.
I thought that the problem should come from the command to access to the 
server : libcurl library

I try to acces to my test-server with the command "curl <url>" and this 
error ocuures

"curl: (60) SSL certificate problem, verify that the CA cert is 	OK. 
Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate 
verify failed"

So I use the command "curl -k <url>" and I acces to the server.

Does an option, like "-k"  : to pass through the verification of the 
certificate, exist ?

Does matlab toolbox be able to work with a server which delivers a 
non-verified ssl certficate ?

thanks

Arnaud
