When sharing WBs via plus I see all db accounts - which is what I dont want

Question

Hi all,
As stated in the subject title, when sharing WB's via plus, users can see the list of all database users in the share workbook payne. Is it possible to change this so that non-discoverer users can be removed from this list...I am particularly concerned that all default database accounts i.e. SYS, SYSTEM, SYSMAN, DBSNMP and so forth appear visible to anyone attempting to share a WB. What I would like to do is have only those accounts that have ben specifically created for my discoverer project to be able to be visible to a user who is sharing a WB. So far I have yet to establish if this can be do, hence why I am posting...
Thanks in advance,
Andrew

Hi Rod
I don't believe this was ever implemented.
Andrew: I have used the ALL_USERS trick myself many times and it works just fine. If you want to filter out the system accounts, as Rod suggested, just create a new SYS view and a synonym for that view as part of each user's creation script. Here is one that I did recently:
When connected as SYS I created this view:
CREATE OR REPLACE VIEW Z_ASC_ALL_USERS
AS SELECT * FROM SYS.ALL_USERS
WHERE SUBSTR(USERNAME,1,3) = SUBSTR(USER,1,3);
I then issued this grant: GRANT SELECT ON Z_ASC_ALL_USERS TO PUBLIC;
I then created these synonyms for my SALES users:
CREATE OR REPLACE SYNONYM SAL_ADMIN.ALL_USERS FOR SYS.Z_ASC_ALL_USERS;
CREATE OR REPLACE SYNONYM SAL_USER.ALL_USERS FOR SYS.Z_ASC_ALL_USERS;
Of course you don't want this synonym being used for non-Discoverer users so don't create it for SYSTEM or any other non-Discoverer account.
What the above does is to let users only see other users whose accounts being with the same 3 characters as their account. Thus if either SAL_ADMIN or SAL_USER were trying to share a report the only user they will see in the list will be the other Sales user.
By the way, there is no need to filter roles as these are filtered by the database naturally thus preventing someone sharing a report with a role that they don't have.
