I was trying to install gforge on debian unstable and the install failed horribly. It had to do with permissions in postgresql database. The installation routine tries to create postgresql user gforge and database gforge and then put some tables into gforge. I m a complete newbie to this so please bear with me. The installation inserted a line "host gforge gforge hostname netmask password". I am trying to install the program as root. The install always failed with error message IDENT authentication failed for user gforge. I restarted the postgresql server at this point, assuming that since the user gforge is added by the installation script and the server is not restarted that could be the problem I was expecting that the routine would instead asked for password since the authentication mechanism described is password. I finally installed the program by using the trust authentication. Can somebody please tell me how to make the installation script work properly without using trust authentication.
