SYMPTOMS
Certificate mapping may not succeed when the &quot;Issuer&quot; or the &quot;Subject&quot; field of a certificate contains a plus sign. For example, the following .cer file excerpt contains a plus sign in the &quot;Subject&quot; field: X509:C=FR,O=ORG-TEST,OU=OU-TESTC=FR,O=ORG-TEST,L=Paris (75),OU=OU-TEST,CN=CN-TEST + SN=TEST ANNUAIRE + G=CARTE 2 Schannel authentications that are based on a certificate that contains this text will not succeed.



CAUSE
This problem occurs because the Certificates Microsoft Management Console (MMC) snap-in and the Secure Sockets Layer (SSL) handshake use different mapping formats. (The Certificates snap-in creates the mapping, and the SSL handshake occurs when Schannel authentication tries to map the certificate to a user.)
