postgres phpgroupware login woes

[Lance Hoffmeyer <lance@august.net>]

Running SARGE.  I have everything installed
and appears to be installed correctly.  If
I login as user postgres I can login to 
a database phpgroupware.  If I am any other
user and I run command 

psql phpgroupware -U postgres -W

I get error 

psql: FATAL:  IDENT authentication failed for user "postgres"

also, I cannot create phpgroupware database from phpgroupware
admin?

What have I got setup incorrectly?
