I take this back, you'll run it right away....
consider two LDAP syntaxes:
( 1.1.1 DESC 'INTEGER restricted to 0 "off" and 1 "on"' )
( 1.1.2 DESC 'INTEGER restricted to -1 "-", 0 "0", and +1 "+" )
(both of ASN.1 syntax INTEGER) and two attributes:
( 22.214.171.124 NAME 'bbit' SYNTAX 1.1.1 )
( 126.96.36.199 NAME 'tbit' SYNTAX 1.1.2 )
Bbit is transferred (in LDAP) as "off" and "on" and
Tbit is transferred (in LDAP) as "-" "0" "+".
Guessing that a DER encoded 1 should be represented as "1"
is wrong in both cases....
BTW, I've similar naming attributes in the real world.
