!!! [Example] - Active Directory [Password Change] [JNDI|JNDI Examples][1]
[Microsoft Active Directory] uses the [unicodePwd] instead of the more common [userPassword] unless you have [Enable UserPassword in Microsoft Active Directory].
Microsoft requires a minimum level of [LDAP encryption|UnicodePwd#section-UnicodePwd-EncryptionRequired]
We have placed the [{$pagename}] [Example] code in our [Code repository|https://bitbucket.org/jwilleke/examples/src/91c2df9b5481b30e5ca213a7baa0ce7e0a04752c/Examples-JNDI/src/com/willeke/samples/ldap/jndi/ADConnection.java?at=master&fileviewer=file-view-default|target='_blank']
The updateUserPassword method is shown below:
%%prettify
{{{
/**
* Update User Password in Microsoft Active Directory
* @param username
* @param password
*/
public void updateUserPassword(String username, String password)
{
try
{
System.out.println("updating password...\n");
String quotedPassword = "\"" + password + "\"";
char unicodePwd[] = quotedPassword.toCharArray();
byte pwdArray[] = new byte[unicodePwd.length * 2];
for (int i = 0; i < unicodePwd.length; i++)
{
pwdArray[i * 2 + 1] = (byte) (unicodePwd[i] >>> 8);
pwdArray[i * 2 + 0] = (byte) (unicodePwd[i] & 0xff);
}
System.out.print("encoded password: ");
for (int i = 0; i < pwdArray.length; i++)
{
System.out.print(pwdArray[i] + " ");
}
System.out.println();
ModificationItem[] mods = new ModificationItem[1];
mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, new BasicAttribute("UnicodePwd", pwdArray));
ldapContext.modifyAttributes("cn=" + username + BASE_NAME, mods);
}
catch (Exception e)
{
System.out.println("update password error: " + e);
}
}
