Hi, I’m trying to insert userCertificate values containing x500UniqueIdentifiers. When the value appears at the SubjectNames, it inserts correctly.
By this I assume there is a validation for the field formatting.
When I have a x500UniqueIdentifier at the IssuerNames it fails to insert.
Is there a specific place where valid attributes and syntaxes for IssuerNames should be declared?
Certificate name validation just uses whatever schema is already loaded into slapd, and x500UniqueIdentifier is in the core schema file so it should already be present in your configuration.
However, subjectNames aren't fully parsed during certificate validation, while issuerNames are. So e.g. a syntax error in subjectName will not be detected at insert time.
Can you post an example certificate? I have a feeling that our DN validator here may not be handling the syntax for x500UniqueIdentifier but would like to double check.
I should also warn you, x500UniqueIdentifier has a bitstring syntax, and this syntax is extremely clumsy in LDAP. Judging from the certificate you sent me, you're trying to use this attribute as a regular octetstring. The two are quite different. E.g. if you have a value in the certificate "x500UniqueIdentifier=ABC" in LDAP this is represented as "x500UniqueIdentifier='010000010100001001000011'B"
I would strongly encourage you to use some other attribute other than x500UniqueIdentifier, and to avoid any attributes that use bitstring syntax as this one does.
The bitstring syntax is intended for data items that are actually an arbitrary string of bits, in particular, a string that may not be aligned on octet boundaries. If the only data you're storing is actually sequences of octets, this is a very inefficient choice of syntax.
