Thanks a lot Michael.
The organizationIdentifier attribute would become very used in the very recent future, for PKIs implementation in Europe.
Qualified CA would use thtat attribute for legal person certificate.
In the ETSI documents, it would be something like organizationName, but different from it.
Teoretically would be something of more distinctive for the organization, i.e. the VAT number with the county code.
By this, I think it could not be such an internal definition for a company.
Thanks again for your kind answer

I look at a lot of different LDAP schema definitions. Until you brought up this I never
saw 'organizationIdentifier' in a LDAP schema. So you probably have to use it in your own
custom object class. Note that LDAP RFCs (e.g. RFC 4524) have X.501(1993) as normative
references.

BTW: I can imagine a lot of diffent IDs for companies, educational/governmental
organizations, etc. So the more interesting question is:
What's the _exact_ semantics of that attribute?

Ciao, Michael.
