GSSAPI support broken. Can't be enabled.

[vidkun]

Describe the bug
Despite the default value of ssh_gssapi_support being true and despite explicitly setting it to true in vars, the sshd config still results in GSSAPIAuthentication no

Expected behavior
I expect GSSAPIAuthentication yes to be set in the sshd_config

Actual behavior
sshd_config contains GSSAPIAuthentication no

OS / Environment
RHEL 7.5
