Access secure websites (SSL) via urlread

Hello,

I need to access a Cacti-Database (http://www.cacti.net/) from Matlab to retrieve individual measurements as .csv-File. To get the .csv-File for a specific time and parameter range I can query the Database via the url. The problem is that we are running our Cacti-Database on a secure SSL Server.

Nevertheless I tried to access the measurements via urlread (or urlread2).
When using urlread with the “Username” and “Password” argument for basic authentication I receive the following error message:

“Error downloading URL. Your network connection may be down or your proxy settings improperlyconfigured.”

There is some information on urlread and SSL in the internet, but it covers mostly the problem of untrusted SSL-Certificates, e.g. http://www.mathworks.de/support/solutions/en/data/1-3SMHXD/index.html?product=SL&solution=1-3SMHXD or http://stackoverflow.com/questions/1638275/handling-an-invalid-security-certificate-using-matlabs-urlread-command.

Since I was told that we use standard / regular SSL-certificates this should not be the problem in my case.

I would appreciate every advice or solution.

Thanks a lot for your help.
