Connection & Crash Problem From Domain Users

Ok. now I have a new problem!
I can use pgadmin without any problem under the local W2K accounts POSTGRES and TESTUSER.
But if I run pgadmin under the domain W2K account MYDOMAIN/CAGILS it connects (and is very slowly) and then when I try
toreach the public database object which is created default, it crashes (stops responding, the log runs in a loop like
crazy).
I can reach to postmaster using psql under MYDOMAIN/CAGILS

Some info about my system conf:

postgres@CAGILS /usr/share/postgresql/data $ tail -n 2 pg_hba.conf
local      all                                          md5
host       all         127.0.0.1     255.255.255.255    md5

postgres@CAGILS /usr/share/postgresql/data $ whoami
postgres
postgres@CAGILS /usr/share/postgresql/data $ psql template1

template1=# select * from pg_users;
