根据sn和给定名称的3个字符动态分配唯一的UID值 [英] Assign unique UID value dynamically based upon 3 character of sn and givenname

问题描述

如何检查UID是否已经存在.如果存在，则为新用户增加一个值，其中包含名字和姓氏的3个字母.如果没有UId，请分配UID的值...并存储在eDirectory中.

How to check whether the UID are present already. If it's present increment one value for the new user with 3 letters of first name and last name. If UId are not present Assign the value of UID ...and store in eDirectory..

    String adminName = "cn=admin,o=novell";
    String adminPassword = "Happiest1";

            totalResults++;

            System.out.println(">>>" + sr.getName());

            // Print out some of the attributes, catch the exception if the attributes have no values
            Attributes attrs = sr.getAttributes();
            if (attrs != null) {
                try {
                System.out.println("   surname: " + attrs.get("sn").get());
                System.out.println("   firstname: " + attrs.get("givenName").get());
                System.out.println("   UID: " + attrs.get("UID").get());
                                    } 
                catch (NullPointerException e)  {
                System.out.println("Errors listing attributes: " + e);
                }
            }

        }

        System.out.println("Total results: " + totalResults);
        ctx.close();

    } 
    catch (NamingException e) {
        System.err.println("Problem searching directory: " + e);
    }
    }
}

}

如果用户名相同，那么它必须在搜索中签入并且如果用户在场，则必须增加其值

if the name oof the user same so it must check in search and if the user is present it must increment its value
