A DESCRIPTION OF THE PROBLEM :
DirContext.createSubcontext(DN, battrs). If the RDN part of the DN is defined again in the BasicAttributes "battrs" with the same value and the attribute name has a case difference (for example "CN" and "cN"), then they are treated as two different attribute values. JNDI then complains about duplicate values defined for the same attribute. In the case where the RDN attribute is a single-valued attribute, JNDI complains that multi-values are being defined for the attribute.

Have an LDAP server running. In your sample code, create a valid DirContext connected to this directory.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
This is the exception thrown-

javax.naming.directory.AttributeInUseException: [LDAP: error code 20 - cn attribute has duplicate value. VALUE: john]; remaining name 'cN=John'

  Bug WorkaroundEnsure that the attribute name in the RDN portion of the DN and the attribute name used in the BasicAttribute definition has the same case - for example, to a "toLowerCase()" from those strings.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Attempt to create a simple DN "cn=John" by using the following snippet
----------------------------------------
// ctx - a valid DirContext

       BasicAttributes battrs = new BasicAttributes();
       battrs.put("objectclass", "top");
       battrs.put("objectclass", "person");
       battrs.put("CN", "John"); // note "CN" is all CAPS
       battrs.put("sn", "Coltrane");

// The "cN" in the DN below differs from the "CN" definition above
// in terms of case. JNDI throws an exception

       ctx.createSubcontext("cN=John", battrs);

// The code below will work because the cases match
       //ctx.createSubcontext("CN=John", battrs);
