[Investigation] Support Kerberos

[fg-j]

Describe the Investigation

Kerberos is a network authentication protocol that's commonly used by .NET Core applications and is the protocol used by Windows Active Directory. Currently, .NET buildpack users cannot use Kerberos-based authentication/authorization for their apps because required libraries are missing from build and run images. Ideally, the Paketo .NET Core buildpack can support apps that rely on Kerberos. This issue is to investigate how that could be implemented.

Possible Solution

Answer (at least) the following questions on the issue:

• Which libraries, exactly, are prerequisites for installing Kerberos on Linux?
• Where can the required libraries be obtained?
• Do these libraries have to be installed by a root user in order to work properly? (i.e. Do they need to be installed in the stack, or can a buildpack install them?)
