When I try to run mongod with GSSAPI authentication mechanism, it seems that there are multiple configuration problems that cause the server to dump core.

Test case #1: no kerberos configuration present on the system at all.

To reproduce, build a docker image from this dockerfile: https://github.com/p-mongo/tests/blob/master/server-gssapi-crash-1/Dockerfile

Actual result: https://gist.github.com/p-mongo/0d32544a51ed7c31fbb557a287609193

Test case #2: kerberos is configured but there aren't any keytabs defined.

To reproduce, build a docker image from this dockerfile: https://github.com/p-mongo/tests/blob/master/server-gssapi-crash-2/Dockerfile

Actual result: https://gist.github.com/p-mongo/a6867c5634a618a20f6eab4d4961762a

Expected result: server produces an error message and exits but does not dump core.
