Initial release

First working version after being forked from node-ldapauth-fork

Added

• New, required, configuration property domainDn, which points to the
  distinguished name of the domain root (e.g. dc=corp,dc=example,dc=com)
• searchFilterByDN configuration property, which defaults to
  (&(objectCategory=user)(objectClass=user)(distinguishedName={{dn}}))
• searchFilterByUPN configuration property, which defaults to
  (&(objectCategory=user)(objectClass=user)(userPrincipalName={{upn}}))
• searchFilterBySAN configuration property, which defaults to
  (&(objectCategory=user)(objectClass=user)(samAccountName={{username}}))
• Users can now be authenticated both by their user principal name, or UPN,
  ([email protected]) and down-level logon name (EXAMPLE\user)
• A user's primaryGroupID is now used to resolve the primary group object and
  prepend it to memberOf and _groups
• Group membership is now fetched recursively and represents all the groups a
  user is an effective member of

Removed

• searchFilter configuration property, which has has been split into
  searchFilterByDN, searchFilterByUPN, and searchFilterBySAN
• cutarelease.py build step, in favour of a manual release workflow. This may
  be reconsidered at a later time.

Changed

• The authentication process now attempts to bind the user's credentials first.
  Subsequent LDAP queries use the client bound to the user's credentials
• Groups are now fetched by default instead of on-demand
• searchBase now defaults to the value of domainDn and isn't required to be
  explicitly set
• groupSearchFilter now defaults to
  (&(objectCategory=group)(objectClass=group)(member={{dn}}))
• Dependency versions now use caret (^), except for ldapjs, which refers to
  master, pending a future release
