LDAP: error code 67 - NOT_ALLOWED_ON_RDN: failed for Modify Request

Question

I am not able to modify attributes in eclipse.Getting error Modify operation attempts to delete RDN attribute values in use for 2.5.4.3 on entry 2.5.4.3=some person2,2.5.4.11=company1,2.5.4.6=sweden,0.9.2342.19200300.100.1.25=jayway,0.9.2342.19200300.100.1.25=se and violates schema constraints

using this code to modify attributes: Attribute attr = new BasicAttribute("cn", "new"); ModificationItem item = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, attr); lt.modifyAttributes(dn, new ModificationItem[] {item});

        lt.modifyAttributes(context);
