I have a branch "ou=people" where RDN are in the form "X1234" and NEVER change for one people.
Ex. : uid=X1234,ou=people,dc=example,dc=org
In this node, I have the login under "eduPersonPrincipalName" attribute which MAY change.
Some applications doesn't allow us to define which login to use and so take "uid" attribute by default, not so cool.
Is there any possibility in OpenLDAP to duplicate dynamically an OU with another RDN to have for example : uid=sylvain,ou=peoplebis,dc=example,dc=org ?
