<p class="MsoNormal">Hi Team,<o:p></o:p></p>

<p class="MsoNormal">We have found that the Pacemaker certificate is not generated with SubjectAlternativeName.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please find the general guidelines :<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In case<i> client certificates are required, verification of the client identity SHOULD use the first matching subjectAltName field of the client certificate to be compared with an authorization identity present in a local or central AA
database. <o:p></o:p></i></p>
<p class="MsoNormal"><i>To mitigate the Man-in-the-Middle risk, the server identity verification is RECOMMENDED to be done as well. A client can accept several server certificates in certificate validation issued by the same trusted CA.<o:p></o:p></i></p>
<p class="MsoNormal"><i><o:p> </o:p></i></p>
<p class="MsoNormal"><i>After certificate chain validation, the TLS client MUST check the identity of the server with a configured reference identity (e.g., a hostname). The clients MUST support checks using the subjectAltName field with type dNSName. If the
certificate contains multiple subjectAltNamevalues then a match with any one of the fields is considered acceptable. <o:p></o:p></i></p>
