Say for example "123" is in your password history.
Create and admin LdapContext with a PasswordRequestControl. (ctx)
ModificationItem[] mods = new ModificationItem[1];
mods[0] = new ModificationItem(ctx.REPLACE_ATTRIBUTE, new
BasicAttribute("userPassword","123")); // try to set the password to entry in
history
try {
//response controls set in ctx here
ctx.modifyAttributes(strDn, mods);
} catch (InvalidAttributeValueException e){
// response control will be null here.
e.printStackTrace(); // below
}

have checked the code but didn't find any obvious issue, do you have a test
case that I can use to reproduce?
