I've seen lockbox issues and have had to run through something like this to resolve them...

cd /smas/SMAS/jboss/standalone/bin

./cstadmin initialize -overwrite ../data/cst -passphrase=xxxxxx

./cstadmin sign-file SmcLocalDirectory -cstdir=../data/cst -passphrase=xxxxx

If the cstadmin command fails, verify that you are pointing to the following libraries:

Linux:          export LD_LIBRARY_PATH=../lib:$LD_LIBRARY_PATH

Windows:   set PATH=..\lib;%PATH%;
