Hi,
I am trying to integrate ISE 2.2 with the SMS gateway from Clickatell. Unfortunately I have not had any success. I found some guides here on the community, but they have not helped. I want to set up a 1-way integration via HTTPS GET.
Pasting the required URL into a web browser works fine, but it is not working from the ISE. The problem does not seem to be a URL problem, but a certificate problem.
When I try and send a notification from the Sponsor portal I get a error.
When I manually try to send a test SMS from the Guest account type page I get a more detailed error:
When I take a look at the traffic on the proxy I can see that the Server is sending its certificate back and I can see the serial number of the CA certificate that signed it.
The serial number of the CA certificate that signed the server certificate matches what is in the Trusted Certificate store of the ISE.
The next thing I see in my packet trace is the ISE reporting a error back to the server "Certificate Unknown"
If anyone has any idea what might be going wrong, it would be appreciated.
