IIS 7 Error "A specified logon session does not exist. It may already have been terminated." when using https
asp.net, client-certificates, iis, ssl
Solution
This must be some kind of IIS bug, but I found the solution.
1- Export MyPersonalCA.pfx from IIS.
2- Convert it to .pem:
`openssl pkcs12 -in MyPersonalCA.pfx -out MyPersonalCA.pem -nodes`
3- Convert it back to .pfx:
`openssl pkcs12 -export -in MyPersonalCA.pem -inkey MyPersonalCA.pem -out MyPersonalCA.pfx`
4- Import it back to IIS.
Problem
I am trying to create Client Certificates Authentication for my asp.net Website. In order to create client certificates, I need to create a Certificate Authority first: makecert.exe -r -n “CN=My Personal CA” -pe -sv MyPersonalCA.pvk -a sha1 -len 2048 -b 01/01/2013 -e 01/01/2023 -cy authority MyPersonalCA.cer Then, I have to import it to IIS 7, but since it accepts the .pfx format, i convert it first ``` pvk2pfx.exe -pvk MyPersonalCA.pvk -spc MyPersonalCA.cer -pfx MyPersonalCA.pfx ``` After importing MyPersonalCA.pfx, I try to add the https site binding to my Web Site and choose the above as SSL Certificate, but I get the following error: Any suggestions?
