cpkiIssuerCertFileName
cpki Issuer Cert File Name
1.3.6.1.4.1.9.9.505.1.1.2.1.10
The name of the file storing the issuer certificate. It is a unix style '/' seperated string representing the absolute path of the file in the file system of the device. If there is no issuer certificate obtained yet, the value of this object will be a zero length string. This object gets its non-zero length string value after a successful 'caauth' PKI support action triggered on the object cpkiAction. This object gets set to zero length string when the issuer certificate is deleted through a successful 'cadelete' action triggered on the object cpkiAction.
