Hi, I'm using JNDI to update an Active Directory. Now I'm facing the
following problem:

When I try to add a value to a multiple attribute (department), I get
the following error:

20:59:11,390 FATAL [LdapSlave.java:95] [LDAP: error code 19 - 00002081:
AtrErr: DSID-031D0809, #1:
    0: 00002081: DSID-031D0809, problem 1005 (CONSTRAINT_ATT_TYPE), data 0,
Att d (description)

It doesn't happen when I add or update a single value attribute.

The snippet for the update is as follows:

private void UpdateRegister(Hashtable db2Hash,String dn) {

        for (Iterator it=db2Hash.entrySet().iterator(); it.hasNext(); ) {
           
           Map.Entry entry = (Map.Entry)it.next();
           String key = (String)entry.getKey();
           String value = (String)entry.getValue();
           String ldapvalue = (String)ldapValsTable.get(key);
           ModificationItem[] mods=null;
           boolean doMod = false;
   
           if ( value.length() == 0 && ldapvalue == null ) {
               continue;
           }
           if ( ldapvalue == null && value.length() > 0 ){
               l.info("atributo \""+key+"\" no existe, creandolo con valor
\""+value+"\"");
              
               //agregar atributo a ldap ... funciona solo con single-valued
               mods = new ModificationItem[1];
               mods[0] = new ModificationItem(DirContext.ADD_ATTRIBUTE, new
BasicAttribute(key, value));
               doMod=true;
           }
           else if ( value.length() == 0 && ldapvalue != null ){
               mods = new ModificationItem[1];
               mods[0] = new ModificationItem(DirContext.REMOVE_ATTRIBUTE,
new BasicAttribute(key));
               l.debug("Borrando atributo: "+key);
               doMod=true;
           }
           else if ( value.compareTo(ldapvalue) != 0) {
               mods = new ModificationItem[1];
               mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE,
new BasicAttribute(key, value));
               doMod=true;
               l.info("Diferencia encontrada: "+key+":"+value+"/"+ldapvalue);
           }
           else
               l.info("No se encontraron diferencias para : "+key+":"+value);
   
            try {
                if ( doMod && !isPreviewOnly )
                    ctx.modifyAttributes(dn, mods);
            } catch (NamingException e) {
                l.fatal(e.getLocalizedMessage());
            }

       }

Any ideas?

Thanks in advance
