使用LDAP / Java启用Active Directory用户

我正在尝试使用LDAP和Java（1.4）在Active Directory中启用用户。 但是我一直收到以下错误：

com.sun.jndi.ldap.LdapCtx.c_modifyAttributes（LdapCtx.java:1432）中的com.un.jndi.toolkit.ctx.ComponentDirContext.p_modifyAttributes（ComponentDir Context.java:255）中的java.lang.NullPointerException位于javax.naming.directory.InitialDirContext.modifyAttributes的com.sun.jndi.toolkit.ctx.PartialCompositeDirContext.modifyAttributes（Partial CompositeDirContext.java:161）中的.jndi.toolkit.ctx.PartialCompositeDirContext.modifyAttributes（Partial CompositeDirContext.java:172） （InitialDirContext。java：146）at.ideal.LDAP.newuser.main（newuser.java:61）线程“main”中的exception

我已经确认我的用户有密码，我似乎无法将其状态更改为活动状态

我的代码：

public static void main(String[] args) { String userName = "cn=Albert Einstein,ou=Accounts,DC=PORTAL,DC=COMPANY,DC=BE"; String groupName = "cn=Administrators,cn=Roles,DC=PORTAL,DC=COMPANY,DC=BE"; boolean isDisabled = false; try { System.out.println("Creating initial directory context..."); LdapContext ctx = new InitialLdapContext(X_Ldap.getEnvironment(), null); Attributes attrs = new BasicAttributes(true); attrs.put("objectClass", "user"); attrs.put("cn", "Albert Einstein"); String newQuotedPassword = "\"Pass123\""; byte[] newUnicodePassword = newQuotedPassword.getBytes("UTF-16LE"); attrs.put(new BasicAttribute("unicodePwd", newUnicodePassword)); attrs.put(new BasicAttribute("msDS-UserAccountDisabled", "FALSE")); System.out.println("Creating context..."); Context result = ctx.createSubcontext(userName, attrs); System.out.println("Created account for: " + userName); System.out.println("Creating context..."); Context result = ctx.createSubcontext(userName, attrs); System.out.println("Created account for: " + userName); try { ModificationItem member[] = new ModificationItem[1]; member[0] = new ModificationItem(DirContext.ADD_ATTRIBUTE, new BasicAttribute("member", userName)); ctx.modifyAttributes(groupName, member); System.out.println("Added user to group: " + groupName); } catch (NamingException e) { System.err.println("Problem adding user to group: " + e); } ctx.close(); System.out.println("Successfully created User: " + userName); } catch (NamingException e) { System.err.println("Problem creating object: " + e); } catch (IOException e) { System.err.println("Problem creating object: " + e); } } 

PS：我正在使用AD LDS作为我的活动目录

找到它：需要使用DirContext.ADD_ATTRIBUTE而不是DirContext.REPLACE_ATTRIBUTE
