Answer 1

jTDS is inferior to Microsoft's JDBC driver (in particular, it cannot figure out the types of parameters in a prepared statement)

Yes, you can authenticate to MS SQL Server using Active Directory authentication, as Active Directory is just Kerberos + LDAP, which are open source and implemented on Mac

Kerberos config /etc/krb5.conf :

[libdefaults]
default_realm = YOUR_REALM.NET

[realms]
YOUR_REALM.NET = {
    kdc = host.your-domain.net
}

I needed to use the fully qualified domain name of the KDC, not just the domain name

JDBC Connection String:

jdbc:sqlserver://$host;database=$db;integratedSecurity=true;authenticationScheme=JavaKerberos

If $host does not have an SPN of MSSQLSrv/$host, add serverSp=$SPN to the JDBC connection string
