java使用未绑定sdk在ApacheDS服务器中搜索组内的用户

Question

我使用ApacheDS作为目录服务器&UnboundID作为LDAP SDK，用于输入用户及其相关组。我正在跟踪一个链接

http://ldapwiki.willeke.com/wiki/Tips%20using%20UnboundID%20LDAP%20SDK

其中他们使用了CompareRequest方法来确定用户是否是特定组的成员

我针对这个方法编写的代码是这样的

//input ---- uid = "rohit.joshi" and groupName = "Java" public boolean isUserMemberOfGroup(String uid, String groupName) { boolean answ = false; LDAPConnection connection = connect(); try { //userDN -- uid=rohit.joshi,ou=users,o=wipro String userDN = "uid=" + uid + ",ou=users," + LDAP_BASE_DN; //groupDN -- cn=Java,ou=groups,o=wipro String groupDN = "cn=" + groupName + ",ou=groups," + LDAP_BASE_DN; CompareRequest compareRequest = new CompareRequest(userDN, "uniqueMember", groupDN); CompareResult compareResult = connection.compare(compareRequest); if (compareResult.compareMatched()) { // The user is a member of the group. System.out.println("user is a member of group"); } else { // The user is not a member of the group. System.out.println("user is not a member of group"); } } catch (LDAPException e) { e.printStackTrace(); } return answ; }

显然，在ApacheDS中，“uniqueMember”没有这样的属性

LDAPException(resultCode=16 (no such attribute), errorMessage='NO_SUCH_ATTRIBUTE: failed for MessageType : COMPARE_REQUEST
Message ID : 1
    Compare request
        Entry : 'uid=mahesh.joshi,ou=users,o=wipro'
        Attribute description : 'uniqueMember'

尝试使用'member'而不是'uniqueMember'

工作示例：

public static void main(String[] args)
{
    LDAPConnection connection = new LDAPConnection();
    try
    {
       connection.connect("localhost", 10389);
    }
    catch (LDAPException e)
    {
    // TODO Auto-generated catch block
       e.printStackTrace();
    }
    String attributeName = "uniqueMember";
    String assertionValue = "uid=mahesh.joshi,ou=users,ou=sevenSeas,dc=example,dc=com";
    String entryDN = "cn=Java,ou=groups,ou=sevenSeas,dc=example,dc=com";
    CompareRequest compareRequest = new CompareRequest(entryDN, attributeName, assertionValue);
    CompareResult compareResult = null;
    try
    {
       compareResult = connection.compare(compareRequest);
       if (compareResult.compareMatched())
       {
           System.out.println("The user: " + assertionValue + " is a member of the group: " + entryDN);
       }
       else
       {
           System.out.println("The user: " + assertionValue + " is NOT a member of the group: " + entryDN);
       }
    }
    catch (LDAPException e)
    {
    // TODO Auto-generated catch block
       e.printStackTrace();
    }
}

设置一个与您的场景尽可能接近的示例。 -吉姆
