Cisco Bug: CSCte63806 - Doc: VPNClient: document CvpndSignHash
Feb 22, 2014
- Cisco VPN Client
Known Affected Releases
Symptom: VPN Client users with smartcards always need to re-authenticate at rekey or get just disconnected after upgrading past version 5.0.4. Conditions: This is because of a fix that went into the vpnclient for CSCsm82775. That bug was because some clients need to re-authenticate at rekey, but the old client was not doing this causing the clients to disconnect. To fix this a parameter was introduced: CvpndSignHash If you configure CvpndSignHash=1 in the main section of vpnclient.ini then the vpnclient will 'cache' the authentication. With CvpndSignHash=0 or nothing configured, so the default., the authentication will not get cached and the user will get prompted to re-authenticate. The 'hash' in the parameter is due to the technical details: the hash signing of the private key is done by vpngui.exe instead of by cvpnd.exe (the main VPN service) by default now. This is only for Windows XP or higher.
