I try with another user and my original code worked.... so... aparently the account had problems...

Hi,Finding the user was not the problem. I can find the user using OID and userID.The line that give me the exception was:dirClient.updateLocalUser(testUser, "oldPassword", "newPassword");Maybe the ALC version I have has a bug...I will keep trying...thanks,

ALC Version: ALC ES2.5The class DirectoryManager has a method called uploadLocalUser. I created a DSC in java and deployed into ALC. There were no error or warnings.The class is defined here: http://help.adobe.com/en_US/livecycle/11.0/ProgramLC/javadoc/com/adobe/idp/um/api/DirectoryManager.html#upda...
