Well i wrote my own SynchronizingLoginModule based on an old version of this class (found on the anonym svn, for jboss portal 2.6) This old version returns an empty string when the password is asked, and the one present in portal 2.7.1 return a null string. Now i don't have any bug, and the user is correctly created in jboss portal database! (his password is blank, but we don't care, it is just for the correct functioning of portal, login & password are checked in CAS) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217923#...
