+
+Doesn't work with a non-iterable nsswitch source
+
+Currently, "finger tabbott" works by iterating through the list of users
+on the system using getpwent and checking if any of them match "tabbott".
+
+Some nsswitch backends (including Hesiod and LDAP[1]) do not support
+iterating through the complete list of users. These nsswitch backends
+instead only fully support looking up a user's information by username or
+uid.
+
+So, if tabbott is a user whose nsswitch information comes from LDAP, then
+"finger tabbott" will incorrectly report "finger: tabbott: no such user."
+"finger -m tabbott" does work correctly, however, because it looks up the
+matching username using getpwnam.
+
+A fix for this is to always look up an argument to finger for a username
+match, and having -m only control whether finger searches the entire user
+database for real name matches. Patch attached.
+
+This patch has the advantageous side effect that if there are some real
+name matches and a username match, finger will always display the username
+match first (rather than in some random place in the list).
+
+ -Tim Abbott
+
+[1] with LDAP, it is typically the case that one can iterate through only
+the first 100 results from a query.
