Absolutely; I certainly do not blame Shibboleth for the deficiences in 
Oracle's module. However, I do blame the wiki page for misleading me 
into thinking that Oracle's module did support keytab verification. (I'm

Fortunately, I tested whether the module used the keytab for 
verification or not before deploying it.

OK. I guess I was just thinking that the wiki is "semi-official", since 
the wiki is where you end up when you click on "Documentation" on But of course, anyone can edit it.
