 * ldap_add - initiate an ldap add operation.  Parameters:
 *
 *      ld              LDAP descriptor
 *      dn              DN of the entry to add
 *      mods            List of attributes for the entry.  This is a null-
 *                      terminated array of pointers to LDAPMod structures.
 *                      only the type and values in the structures need be
 *                      filled in.
 *
 * Example:
 *      LDAPMod *attrs[] = {
 *                      { 0, "cn", { "babs jensen", "babs", 0 } },
 *                      { 0, "sn", { "jensen", 0 } },
 *                      { 0, "objectClass", { "person", 0 } },
 *                      0
