Note that this is not a wise decision since surenames are hardly
unique even within a single department of a single institution, but
that's your choice...

How to achive that:
Documentation Home: https://wiki.shibboleth.net/confluence/display/SHIB2/
Configure -> https://wiki.shibboleth.net/confluence/display/SHIB2/Configuration
Identity Provider (IdP) "More..." -> Support a new Name Identifier
