krb5.conf parameter expansion #429
Conversation
Fixes jcmturner#428 Support parameter expansion for default_ccache_name, default_client_keytab_name and default_keytab_name. Additionally, parse krb5-config if it exists, for defaults that aren't set in krb5.conf. This should support MIT sites that use a self-maintained version or distros that change MIT defaults.

I have been trying to avoid global variables. Could this be a local variable to the LibDefaults.parseLines() method function?

I like to avoid using Go's init function as if there are issues with it during runtime it can be confusing to debug as it was not explicitly called by another function. Could we initiate the expandMap within the LibDefaults.parseLines() method?

I think we should make this a private function.

These things are unix specific and gokrb5 is intended to be platform independent. I'm not sure I completely understand the purpose of needing things lie exec_prefix in a krb5.conf. I need to understand this more so we can figure out what would be an appropriate platform independent approach.
