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.

And while X.520 introduced this attribute, X.521 hasn't included it in any class.
 
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?

There is no "exact" semantics for this attribute.
ETSI EN 319412-1 has a proposed one that is to be used in the eIDAS context (using national trade register number or a national VAT number), but this semantics is not mandatory.

Francesco, as said, you'll have to create your new class for this.
Either you create an auxiliary class so this attribute can be added to any entry, or you create a brand new structural class containing all the bells and whistles you want.
 
Ciao, Michael.
