What went wrong?

Loading gssapi on windows throws "OSError: Could not find KfW installation" when there are multiple kinit.exe in the PATH. Specifically, in the case of having the Java JDK being installed it satisfies the "kinit.exe" under that path and ignores the subsequent one pointing to the kerberos installation.

How do we reproduce?

1. Install Kerberos somewhere other than c:\Program Files\MIT\Kerberos
2. Install JDK
3. Add the jdk\bin directory to the path before the Kerberos installation path

Making Kerberos the first directory in the path is obviously a workaround, but ideally the logic for finding the kerberos installation could be enhanced a bit to use "which --all" and validate the correct path.
