Gladly. Running as root vs running as tss user in this case shouldn't
have an impact. The daemon isn't able to open the shared object based on
the name you've provided. This library has been renamed in the tpm2-tss
repo in anticipation of our next major release. It is now called
"libtss2-tcti-mssim.so".

Dan just updated the man page for the daemon so that we're using the
right names in the examples:
https://github.com/tpm2-software/tpm2-abrmd/commit/98dd707fe58d839e2e642e2c9108c77e277b94f2

This of course assumes you're working off of the 'master' branch of the
repos of course.

Hope this helps,
Philip
