I am trying to create a multi-valued RDN with OpenSSL using a config file and the openssl req -x509 command, without success. According to the 2006 thread "Multi-value RDNs and openssl.cnf format" <http://openssl.6102.n7.nabble.com/Multi-value-RDNs-and-openssl-cnf-format-td7925.html>, one is supposed to do this by prefixing the keys in the distinguished_name section with "+" on subsequent entries to add to a multi-valued RDN, such as: [distinguished_name] ST = California +L = Los Angeles +postalCode=90013 Unfortunately, that (still) does not work. The error from openssl req -x509 (etc.) is: problems making Certificate Request 30008:error:0D06407A:asn1 encoding routines:a2d_ASN1_OBJECT:first num too large:.\crypto\asn1\a_object.c:109: 30008:error:0B083077:x509 certificate routines:X509_NAME_ENTRY_create_by_txt:invalid field name:.\crypto\x509\x509name.c:285:name=+L I was successful at making a multi-valued RDN with the -multivalue-rdn and -subj options, but that is not as versatile/scriptable. Any ideas? Sean PS It looks like it may be related to the behavior in auto_info (req.c) X509_NAME_add_entry_by_txt (x509name.c), in particular, the relationship between the variables mval, type, and p in auto_info (req.c). Could be a bug.
