Change Password script on Liferay Portal - passwords

Question

I have created a dashboard using Liferay Portal and I also have a seperate User management Server (OpenLDAP).
My requirement is when user changes the password through
Liferay portal → My Account → Password → Save, it should automatically be updates in my LDAP server.
For that I have to incorporate some changes in password script of Liferay portal.
Where can i find the password script? or lets say, which script is called when user changes the password and clicks save.

Answer 1

You can use a hook to update the password. Since ultimately liferay will store the password in the database through a method in UserServiceImpl and UserLocalServiceImpl and the database table User_ is going to be updated which is represented by the model User.
So can use any of the following approaches:
Use a Wrapper hook. Write your custom code in your *UserServiceWrapper class's updateUser method.
Or use a Model Listener hook. Create a UserListener and use the method onAfterUpdate and/or onAfterCreate to write your custom code.
Have you also considered using the Portal Settings LDAP export option?
Portal Settings → Authentication → LDAP → Import / Export, more information in Liferay User-guide

In ../deploy/ROOT.war/html/portal folder there is update_password.jsp which is responsible for presenting the UI.
If you check this JSP page, the action that gets called is /portal/update_password
If you check struts-config.xml file present in ../deploy/ROOT.war/WEB-INF folder, you will get the corresponding action which gets invoked. Below is the code,
<action path="/portal/update_password" type="com.liferay.portal.action.UpdatePasswordAction">
<forward name="portal.update_password" path="portal.update_password" />
</action>
If you check the class UpdatePasswordAction present in com.liferay.portal.action package then the relevant code which changes the password of the User is below,
protected void updatePassword(HttpServletRequest request, HttpServletResponse response, ThemeDisplay themeDisplay, Ticket ticket)
throws Exception
{
....
UserLocalServiceUtil.updatePassword(
userId, password1, password2, passwordReset);
..
}
