Alfresco is an enterprise content management solution. It can synchronize its user repository with Active Directory. When users are synchronized from Active Directory, Alfresco does not allow users to edit properties that are being synchronized with Active Directory. By default Alfresco synchronizes certain user attributes to Alfresco Person object properties. Some of these include users' first name and last name. If you want to include custom attributes you need to make sure that you set them up in the Alfresco configuration files. There are different ways to modify and extend Alfresco. The safest way is to never touch any Alfresco properties in the WEB-INF/classes folder. They would get overridden when Alfresco is updated. Alfresco recommends using Spring Beans to extend and override configuration. Here is a wiki page from Alfresco that talks about how to achieve this http://wiki.alfresco.com/wiki/Alfresco_Subsystems#Spring_Bean...
