Now that LDAP supports an `insecureSkipVerify` option, clarify that
`insecureNoTLS` is an extremely bad choice and as such we may drop
support for 389 in the future.
However, since we send plain text passwords from our frontend to our
backend, this probably gets us into a bigger conversation about dex's
TLS story. For example when terminiation is approporate. cc'ing
@dghubble for thoughts on how that might apply to our internal uses.
We probably want an overaching security doc at some point, but that
can be another PR.
Specify "DN" as attribute name to return, but will only work if not present in ldap.Entry.Attributes
Use when full DN is stored in groupSearch's userAttr
Using the default KUBECONFIG environment variable to indicate that
the Kubernetes tests should be run lead to cases where developers
accidentally ran the tests. This has now been changed to
"DEX_KUBECONFIG" and documentation hsa been added detailing how to
run these tests.
Additionally, no other storage reads environment variables for its
normal configuration (outside of tests) so the Kubernetes storage
no longer does.
Overall, be less surprising.
