The example statements from tagish.login (telling the code how your
database looks like) will need to go into whatever file the version of
the Shib IDP you're using uses as JAAS config file.

The Shib IDP by default certainly doesn't look at a file called
tagish.login

For IDPv2 that was /opt/shibboleth-idp/conf/login.config by default,
for IDPv3 according to the documentation
https://wiki.shibboleth.net/confluence/display/IDP30/AuthenticationConfiguration
https://wiki.shibboleth.net/confluence/display/IDP30/PasswordAuthnConfiguration
https://wiki.shibboleth.net/confluence/display/IDP30/JAASAuthnConfiguration
that would require changes to
/opt/shibboleth-idp/conf/authn/password-authn-config.xml and
/opt/shibboleth-idp/conf/authn/jaas.config, at least.
