Currently the Dockerfile attempts to wget the IdP software from:
http://shibboleth.net/downloads/identity-provider/latest/shibboleth-identity-provider-3.2.1.tar.gz
However, this is not a stable URL, as the name of the tar.gz file changes with each release of Shibboleth IdP.
A less fragile solution would be to either use the URL of a fixed version e.g.:
http://shibboleth.net/downloads/identity-provider/3.2.1/shibboleth-identity-provider-3.2.1.tar.gz
or to use something like
wget -P download -A "shibboleth-identity-provider-*.tar.gz" -e robots=off -r -nd -np https://shibboleth.net/downloads/identity-provider/latest/
