In the AKID extension the following rules apply: (See https://tools.ietf.org/html/rfc5280#section-4.2.1.1) 1. The "keyIdentifier" (keyid), if present, must match the subject key ID of the issuing CA's certificate (not the issuer of the issuer) 2. The "authorityCertSerialNumber", if present, must match the serial number of issuing CA's certificate (not the issuer of the issuer) 3. The "authorityCertIssuer" (DirName), if present, must match the issuer DN of the issuing CA's certificate. It is part 3 that is perhaps confusing you a bit, because it is also the subject DN of the issuing CA's issuer. > Could you help me, please. I'm really stucked at this problem :( The above requirements are not met by D2, because C2's issuer: OBJECT :INN NUMERICSTRING :007710474375 OBJECT :OGRN NUMERICSTRING :1047702026701 OBJECT :emailAddress IA5STRING :dit@xxxxxxxxxxx OBJECT :streetAddress UTF8STRING :125375 г.
