[postgres@server /var/lib/pgsql]$ createuser --no-adduser --no-createdb -P egroupware
[postgres@server /var/lib/pgsql]$ createdb --encoding=utf-8 --owner egroupware egroupware

and write this line on pg_hba.conf :

# TYPE DATABASE USER CIDR-ADDRESS METHOD
host egroupware egroupware 127.0.0.1/32 password

But continue the error , and not install...with the button : Re-Chek my database
