Our documentation for Kerberos on Linux has a section entitled "Use a Config File" and shows the parameter you use to implement Kerberos in both YAML and .ini formats:

setParameter:
   authenticationMechanisms: GSSAPI

setParameter=authenticationMechanisms=GSSAPI

On the other hand, our documentation for Kerberos on Windows does not have this same section. The examples on this page only mention command line arguments even though a config file will work as well. It is the same parameter for both OS so its not a major issue but it should probably be added for clarity's sake.
