Some pointers. The  client authentication is handled here:
http://www.postgresql.org/docs/9.0/interactive/auth-pg-hba-conf.html

In your pg_hba.conf  there is at least one authentication method set to ident. 
That is described here:
http://www.postgresql.org/docs/9.0/interactive/auth-methods.html#AUTH-IDENT

authentication.  For security you want md5.
There may already be a line with that method in your pg_hba.conf. In pg_hba.conf 
first matching line wins, so if there is a line with ident first it will take 
precedence. 

If this is too confusing post your pg_hba.conf(unless of course there are 
security issues) and we can go from there.
