ssl_server_issuer

Certificate chain member for the server. The server reads the certificates in the chain in the order they are presented in this parameter.

ssl_server_issuer = chain_member

The same certificate can appear in multiple places in the certificate chain.

The certificates must be in PEM, DER, PKCS#7, or PKCS#12 format. A DER format file can only contain a single certificate, it cannot contain a certificate chain.

See File Names for Certificates and Keys for more information on file types for digital certificates.
