This patch applies to Bacula version 2.2.4 (possibly earlier 2.2.x versions)
and fixes a Storage daemon authentication problem with the FD. This fixes
bug #953. The patch also adds a bit of additional debug code and significantly
strengthens the SD session key.
Apply it to 2.2.4 with:
cd <bacula-source>
patch -p0 <2.2.4-sd-auth-fail.patch
make
...
make install
