Description of problem:
I'm trying to connect to an Junos Pulse server with openconnect.
The shipped version of openconnect does not understand the --protocol option and fails to connect.

Version-Release number of selected component (if applicable):
openconnect-7.06-1.el7.x86_64

How reproducible:
always; try to connect with 7.06.

Steps to Reproduce:
1. 
openconnect -u user --servercert sha256:7580d2efd2f0d7583c4b2e90cf647c2fec70e165d...54 	https://xyz.de/service

2. 
Server SSL certificate didn't match: sha1:21a4...32dc6b4cc9ce549d3e
SSL connection failure: Error in the certificate.
Failed to open HTTPS connection to xyz.de
Failed to obtain WebVPN cookie

3.
I rebuild openconnect 7.08 and tried with --protocol=nc:

openconnect -u user --protocol=nc --servercert sha256:7580d2efd2f0d7583c4b2e90cf647c2fec7...54 \
	https://xyz.de/service

GET https://xyz.de/service
Connected to xxx.yyy.aaa.22:443
SSL negotiation with xyz.de
Server certificate verify failed: signer not found
Connected to HTTPS on gate.fraport.de
Got HTTP response: HTTP/1.1 302 Found
GET https://xyz.de/xxx/auth/url_5/welcome.cgi
SSL negotiation with xyz.de
Server certificate verify failed: signer not found
Connected to HTTPS on xyz.de

Actual results:
no connection


Expected results:
connection

Additional info:
- it works fine with openconnect 7.08 and option --protocol=nc
- with openconnect 7.06 the server answers with a sha1 certificate(?) and fails
