For the schema differences you can change identity-profile.xml file. http://wiki.jboss.org/wiki/Wiki.jsp?page=PortalSVNRepo Identity module is built separately from the portal. For 2.6.4 you need: http://anonsvn.jboss.org/repos/portal/modules/identity/tags/JBP_IDENTITY_... DB implementation: http://anonsvn.jboss.org/repos/portal/modules/identity/tags/JBP_IDENTITY_... LDAP implementation: http://anonsvn.jboss.org/repos/portal/modules/identity/tags/JBP_IDENTITY_... The thirdparties in main portal build are downloaded on the first run. Simply use ./build/build.xml (or run ./build/build.sh). It'll work the same for the identity module. An option for you would be to use custom LoginModule implementation to authenticate and then synchronize into portal DB using SynchronizingLoginModule. I don't know if it fits your usecase.
