[Webcollab-users] unable to connect to database after installation

[Bhuvan K. <bh...@sw...>]

I have debian OS on which i am able to run drupal instances with any 
problem I use postgresql as the database. While trying to install 
webcollab i get a problem with connecting to the database. I did the 
following steps.

1) unpack webcollab-3.00.tar.gz to collab directory in /var/www
2) changed permission of /var/www/collab/config/config.php to 777
3) changed permission of /var/www/collab/files/filebase to 777

4) create a database and user with these commands
createuser collab --pwprompt --encrypted
createdb collab --owner=collab


5) access the setup page through http://localhost/collab/setup.php

6) select english as the language

7) select no at the option of creating a database by webcollab

8) give the credentials of database and other options.

when i select re-enter i get ok at the database name and other options 
but database user and database password don't give an error or warning. 
at the end it says that webcollab was successfully installed and when i 
select write the configuration file it gives me a page that says unable 
to connect to database but user and password of webcollab are admin and 
admin123.

I am unable to figure out the problem. I checked with postgresql config 
files in /etc/postgresq/9.1/main/... everything is fine in their.

Bhuvan
