Constraint violation (19) error in Active directory

When i m adding user oject in ldap, i m getting error of constraint voilation(19). I know the reason of problem. The problem is there are 'userprincipalname' and 'sAMAccountName' atrributes value already exist in ldap in same organization unit of same domain.

I want to know, is there any possibility to add duplicate value in user object in ldap?

You used to be able to have duplicate UPN's.

This changed in Windows Server 2012R2. I just ran into this also.

No.

The sAMAccountName attribute is a single-valued attribute and must be unique among all security principal objects within the domain.

The UPN is a single-valued and indexed attribute and must be unique among all security principal objects within the directory forest.
