bug#19404: 25.0.50; Gnus shows self-signed certificate warning when connecting to Gmane

[Dmitry Gutov]

And has been doing that ever since NSM patches were installed, IIRC.

Am I doing something wrong?

Looks like this:

Certificate information
Issued by:          news.gmane.org
Issued to:          Gmane
Hostname:           news.gmane.org
Public key:         RSA, signature: RSA-SHA1
Protocol:           TLS1.0, key: DHE-RSA, cipher: AES-128-CBC, mac: SHA1
Security level:     Weak
Valid:              From 2011-12-04 to 2014-12-03


The TLS connection to news.gmane.org:nntp is insecure for the
following reasons:

certificate signer was not found (self-signed)
certificate could not be verified
