Freeradius + Postgres not working with init.d script

[Baltazar Ruiz]

Hello everyone,

I'm running:
Freeradius 1.1.3 + Postgresql Version: 8.1.9, Release: 1.el5 on CentOS 5

My problem is that when I execute:

    radiusd -sxxx

everything runs fine, but, when I execute:

    /etc/init.d/radiusd start

I get the following error:

Error: rlm_sql_postgresql: Couldn't connect socket to PostgreSQL  
server user at localhost:database
Error: rlm_sql_postgresql: Postgresql error 'could not connect to  
server: Permission denied ?Is the server running on host "localhost"  
and accepting ?TCP/IP connections on port 5432? '
Error: rlm_sql (pgsql-voip): Failed to connect DB handle #0

To me it seems that everything is configured properly because it runs  
fine when executed manually, but I just can't find the way to make it  
work with the init.d script..

Thanks for your help.
