Not using KRB5_KTNAME or KRB5_CONFIG variables

[FF-Ninja]

In my testing the module is not using environment variables KRB5_KTNAME or KRB5_CONFIG as my environment runs inside docker container so unable to modify /etc/krb5* files.

Should it be able to use these variables?

This library just calls the GSSAPI C library which is the one that reads the env vars. It doesn't have any of the logic for reading env vars and configuring things like default keytab locations. Make sure that the environment you are running it in actually has those env vars set in the process and that the underlying GSSAPI C library that this is wrapping actually supports those env vars.
