Hello

We have been using for years and without problems local ident
autentification in the database for our user postgres.

These are the values that we have been using until version 8.3:
pg_hba.conf:
- ------------
local    all         postgres       ident sameuser

pg_ident.conf:
- --------------
sameuser         postgres          postgres

With 8.4, we get this error if we use a map named 'sameuser'.
- -----------------------------------------------------------
FATAL:  Ident authentication failed for user "postgres"
LOG:  no match in usermap for user "postgres" authenticated as "postgres"
CONTEXT:  usermap "sameuser"
- -----------------------------------------------------------

These are the values used with 8.4:
pg_hba.conf:
- ------------
local    all         postgres       ident map=sameuser

pg_ident.conf:
- --------------
sameuser         postgres          postgres

After some investigation, we have found out that everything works
without problems if we change the mapname used by ident to something
different than 'sameuser'.

Is this a bug or have we decided this behavior? I can not find any
documentation explaining that 'sameuser' is not a valid mapname.
