The value is a premium considering Atlassian was valued last year at $3.3B even though it has significantly more enterprisey features/ecosystem in the wiki/issue tracker/CI space, although it's not yet owned the social VCS enterprise/SaaS space.
Atlassian has an interest in dominating the enterprise-side with JIRA (issue tracker) & Confluence (wiki). Atlassian's Github non-Enterprise competitor, Bitbucket, has unlimited private repos for free or $200/enterprise. Atlassian also offers FishEye/Crucible and Stash to compete with GE.
The big plus with JIRA/Confluence are the plethora of free/paid plugins and lots of enterprisey features that aren't available in Redmine/Chili, Trac, etc. without significant work. In those circumstances, IT shops appreciate Active Directory provisioning, fine-grained permissions and such when any of mediawiki, google docs/quip, asana aren't often up to task without lots of extra work. (Yes, deploying Atlassian to production used to be a PITA, but it's much better than it was some years ago.)
Atlassian's HipChat is basically a 37signals' Campfire clone, and Slack/FlowDock are significantly better for most use-cases.
In the CI market, most shops end up deploying Jekins/Hudson because of it's cross-platform slave builder agents and massive plugin ecosystem. I wouldn't use Bamboo. CI needs to be deployed when enterprise can't use TravisCI or similar.
Active Directory is a whole bunch of stuff build on top of something that looks like LDAP except less sucky, and it lets you do many things from setting permissions to sharing printers and deploying software. It's not something to be installed during a lazy Friday afternoon following a 'AD 101' tutorial though.
Yup. Basically, apps that do MS-specific LDAP queries to AD or something emulating it (Samba). It's also often useful for apps to be allow admin users to tweak the actual LDAP queries in case they have a custom enterprise-wise schema. Stanford, for example, used AD as the "single source of truth" with another LDAP setup for *NIX. (In addition to a modified version of MIT Krb5 with AFS integrations.)
