Open LDAP - How to define an additionnal "uid" like attribute equivalent to a RDMS unique key index

Hi all 1) The context My team is working on a corporate directory using Open LDAP 2.4.38, managing about 200,000 employees. Each employee is constructed using a specific object class named ftperson, based on parent object class inetOrgPerson All the ftperson objects are are stored in an branch named ou=people . We use the standard uid attribute for he RDN 's ftperson object to identify an employee. So far, the full DN of an employee is something like : uid=CUID,ou=people,dc=intrannuaire,dc=orange,dc=com with CUID representing an alphanumeric string Precision : the CUID value is precalculated and provisioned by another corporate identity management system that checks and ensures the CUID value is unique. We have a new requirement consisting of adding an additionnal "uid" like attribute named xuid The value of xuid will also precalculated et provisioned by the corporate identity management system that will check and ensure the xuid value is unique. At first, we have choosen to simply add a new attribute to the ftperson object structrure using the following attribute definition : olcAttributeTypes: {76}( ORANGE-AT:77 NAME 'xuid' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE ) 2) My question We'd like to harden the xuid management policy on our Open LDAP server by adding an unicity constraint rule for the xuid attribute equivalent to a RDMS unique key index. I've found and read several LDAP documentations including : => uid attribute définition https://ldapwiki.com/wiki/0.9.2342.19200300.100.1.1 => extented flags https://ldapwiki.com/wiki/Extended%20Flags I've tried several configurations such as : - define xuid attribute using uid as a parent attribute type olcAttributeTypes: {76}( ORANGE-AT:77 NAME 'xuid' SUP uid EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{256} SINGLE-VALUE ) - define xuid attribute using uid as a parent attribute type with additional extended flags olcAttributeTypes: {76}( ORANGE-AT:77 NAME 'xuid' SUP uid EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{256} SINGLE-VALUE X-NDS_NAME 'uniqueID' X-NDS_LOWER_BOUND '1' X-NDS_UPPER_BOUND '64' X-NDS_PUBLIC_READ '0' X-NDS_NONREMOVABLE '0' ) Where injecting the modified configurations , the Open LDAP server seems to accept them (no error message). When we add the xuid attribute to an existing ftperson object, it works But the same xuid value can be set for different ftperson objects and so, the unicity constraint rule for xuid is not respected. :-( Any idea that idea that could help to fix this issue ?
