[stunnel-users] "choose a digital certificate" pop-up in IE

[Lars Braeuer]

Hi Thomas,

try the following settings in the global section of your config:

sslVersion = all
options = NO_SSLv2

The default config seems to have just SSLv3 enabled. Some Internet Explorer versions only work if
TLSv1 is enabled, at least as long as SSLv2 is disabled.

Best regards,

Lars Bräuer
