Group name in which a particular user is member

Question

Hi all,
I would like to be able to get the group name in which a particular user is a member.
I have created 2 groups: CHEFS and EMPLOYEES.
The Chefs are members of both groups. The "normal" Employee is the member only of EMPLOYEE group.
I have the navigation plsql portlet. And I would like to enable any links of this portlet only for chefs. At default these are disabled.
Now I make it with the function get_user_group:
=========================================
create or replace function get_user_group
v_username IN VARCHAR2,
v_groupname IN VARCHAR2
return boolean
as
var_groupname varchar2(50);
begin
select upper(name)
into var_groupname
from portal.wwsec_group
where id in (select group_id from portal.wwsec_flat
where person_id in (select id from portal.wwsec_person
where user_name=upper(v_username)))
and name=v_groupname;
return true;
exception
when no_data_found then
return false;
end;
=====================================
But the user needs DBA privileges to select on the tables of PORTAL-User.
I don't want to give this privileges to user.
Is there any other way to get the usergroup?

There are portal API's that look like they would do exactly what you are asking for. Take a look at the wwsec_api functions, specifically, is_user_in_direct_group or is_user_in_group in http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/PLSQL/DOC/PLDOC_9026/D:/PDK/pdkjuly/pdk/plsql/doc/pldoc_9026/index.html.
These API's are specific to 9.0.2.6. You'll have to ask someone who knows other versions if you are running something else.
