DbLink connection with SSPI authentication fails

Hello,

 

I have installed v9.2 on Windows XP and configured SSPI authentication for a Windows user "Administrateur" in pg_hba.conf

Using psql or Pgadmin, authentication with the user "Administrateur" works without problem.

 

However I couldn't create a connection using DbLink and the Windows user, I tried the following queries but got always the same error.

 

Queries:

 

SELECT  dblink_connect('host=localhost dbname=PortefeuilleValeurs user=Administrateur')

SELECT  dblink_connect('host=localhost dbname=PortefeuilleValeurs user=Administrateur password=')

SELECT  dblink_connect_u('host=localhost dbname=BdTest user=Administrateur')

SELECT  dblink_connect_u('host=localhost dbname=BdTest user=Administrateur password=')

 

Error Message:

ERREUR:  could not establish connection
DETAIL:  FATAL:  authentification SSPI échouée pour l'utilisateur « Administrateur »

********** Erreur **********

ERREUR: could not establish connection
État SQL :08001

 

Remark : Using "postgres" user, DbLink works.

 

Could anyone tell me how to configure SSPI authentication using DbLink ?

 

Thanks a lot !
