Subject "Your user name and password are not defined."
Author Luis Madaleno

I have FB 1.5.2 running in a Suse 9.3 PRO machine.
it runs fine and I can do a select * from rdb$relations sucessfully
using isql.

but if I try to open a DB using IBExpert from a windows machine, I get
this error:
"Your user name and password are not defined. Ask your database
administrator to set up a Firebird login."

I changed the SYSDBA.password file to have masterkey.

my database file has firebird as the group and owner.

what can this be? this is my first FB installation under linux.
