Getting "ident" to work in Windows

Hi,

I'm trying to enable "ident" authentication on my Windows machine using PostgreSQL 9.1

However as soon as I add the following line to pg_hba.conf

host all all ::1/128 ident sameuser

I get an error message when trying to login (after a server reload of course)

psql: FATAL: could not load pg_hba.conf

It is precisely that line above. As soon as I remove it I can logon again (with a username/password of course).

I did verify that my connections are done through IPV6.

Here is the current content of my pg_hba.conf:

--------- snip ----------
# TYPE DATABASE USER ADDRESS METHOD

# IPv4 local connections:
host all all 127.0.0.1/32 md5

# IPv6 local connections:
host all all ::1/128 md5
--------- snip ----------

Ideally I would like to make "ident" to work with a custom map but using "ident tkmap". But that throws the same error which isn't really surprising as "ident tkmap" is not working either.

Is ident not supported on Windows? I could not find anything related to that in the manual.

Thomas
