Joseph Doherty d549a782fd fix(auth): user bind proves the bound account is the entry whose groups it returns (scadaproj#40)
BindMode=User bound as UserBindTemplate({0}) and then returned the groups of
whatever entry (UserNameAttribute={0}) found - two directory lookups that can
name two accounts (Auth-007). Reproduced live against GLAuth: mallory bound as
herself and signed in with boss's Admins group.

After the bind the service now asks RFC 4532 Who-am-I and requires the entry
to be that account (dn: -> DN match; AD u:DOMAIN\name -> sAMAccountName match).
Without a Who-am-I answer only a DN template is provable (bind DN must equal
the entry DN); anything else fails closed as GroupLookupFailed. {0} is
RFC 4514-escaped in DN templates; validator message leads with EXAMPLE\{0}.

Auth 0.4.3 -> 0.4.4 (unpublished).

Joseph Doherty e3d146aa21 fix(auth): canonical username from the entry; refuse empty passwords in both bind modes
- Request UserNameAttribute in the search (de-duplicated, case-insensitive) and return its
  first value as LdapAuthResult.Username, falling back to the typed name (I2).
- The empty-password guard now applies in ServiceAccount mode too: AD treats an empty-password
  simple bind as an unauthenticated bind and reports success (I3).
- Restore the dropped explanatory comments in CompleteWithServiceAccount / SearchUser.
