I did it my way and it works now - but it was a bit sneaky idea
While SSL is working now (I mean vhost file contain SSL info), I copied into Website Webdomain texboxes content of files I own before:
1. SSL Request - content of filename: my.domain.csr
2. SSL Certificate - content of filename: my.domain.crt
3. SSL Bundle - content of filename: COMODOHigh-AssuranceSecureServerCA.crt
Then simply apply SSL Action 'Save Certificate'
file that I previously generated myself for CA Authority (COMODO) for certificate request process.
- domain certificate received from CA.
Then I copied my.domain.key
file to .../web/sssl folder. This file was also created during certificate request process for signing my.domain.csr file. That file replaced created by the ISPconfig one.
But... there is a little problem while restart httpd service:
# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: Apache/2.2.3 mod_ssl/2.2.3 (Pass Phrase Dialog)
