The <RDNSequence> rule describes the GSER encoding of values of the
RDNSequence type, which is syntactically equivalent to the
DistinguishedName and LocalName types. The <RDNSequence> rule
encodes a name as an LDAPDN character string between double quotes.
The character string is first derived according to the
<distinguishedName> rule in Section 3 of RFC 2253 [5], and then it is
encoded between double quotes with any embedded double quotes escaped
by being repeated.
DistinguishedName = RDNSequence
LocalName = RDNSequence
RDNSequence = dquote *SafeUTF8Character dquote
The <RelativeDistinguishedName> rule describes the GSER encoding of
values of the RelativeDistinguishedName type that are not part of an
RDNSequence value. The <RelativeDistinguishedName> rule encodes an
RDN as a double quoted string containing the RDN as it would appear
in an LDAPDN character string. The character string is first derived
according to the <name-component> rule in Section 3 of RFC 2253 [5],
and then any embedded double quote characters are escaped by being
repeated. This resulting string is output between double quotes.
RelativeDistinguishedName = dquote *SafeUTF8Character dquote
The <ORAddress> rule encodes an X.400 address as an IA5 character
string between double quotes. The character string is first derived
according to Section 4.1 of RFC 2156 [2], and then any embedded
double quotes are escaped by being repeated. This resulting string
is output between double quotes.
ORAddress = dquote *SafeIA5Character dquote
7. Security Considerations
This document contains an alternative description of parts of the
Generic String Encoding Rules, but does not replace or alter GSER in
any way. For the full security implications of using GSER, see the
Security Considerations section for GSER [7].
