Hi everybody,
All the problems were coming from the fact that, because of a misunderstanding of mines, I configured neither the jaas authentication context in a extension/jaas-authentication-context.xml, nor a chaining context.
Now I can make work both the jaas Kerberos AD security and the chain with Alfresco security and jaas Kerberos AD security.
I have just one minor problem left. When I use chaining I cannot login from the web using my alfresco users, because the kerberos filter tries to authenticate them in the AD domain and, of course, it can't.
There's a way to make the web client first to authenticate against the Alfresco DB and, if it does not suceed, against AD, or viceversa? I tried a configuration with both the kerberos filter and the standard filter active, with no luck. I also tried them in reverse order with no success.
Thanks in advance for any help
ciao Francesco
