Clarify LDAP feature for competitors
@boleary asked me in chat:
On this page: https://about.gitlab.com/comparison/gitlab-eep-vs-bitbucket-server.html#dropdown we mention that Bitbucket Server doesn't have LDAP support, but on this page they suggest they do: https://confluence.atlassian.com/bitbucketserver/connecting-bitbucket-server-to-an-existing-ldap-directory-776640403.html
Is there a feature parity difference we're getting at there?
The same goes for GitHub Enterprise https://help.github.com/enterprise/2.11/admin/guides/user-management/using-ldap/. We should change the features.yml
to reflect this.
