SQL Developer vs Oracle Administration Assistant for Windows

Question

I'm new to oracle and have logged into the oracle sql developer with a very low privileged user account. I see other users defined, but when I login to the server and open the oracle administration assistant, I don't see any users. The account I'm logging in under is the account the server is using to run oracle. Is there a reason I can't see these other users on the server?
Thanks

The users you are seeing in SQL Developer are authenticated by the database and not Windows; therefore, they are not External OS Users so they won't show up in that list. An external user (i.e. one authenticated by Windows) would need to be created in order to be visible on that list.
If you want to confirm the type of authentication used, you can execute the following query as a user with the ability to query the dba_users view:
select     username,
           authentication_type
from       dba_users
order by   username;Here's a snippet of the output on my local system:
USERNAME                       AUTHENTICATION_TYPE
OE                             PASSWORD
OLAPSYS                        PASSWORD
OPS$LIVERPOOL\MARKWILL         EXTERNAL
ORACLE_OCM                     PASSWORD
ORADEMO                        PASSWORDThe users with PASSWORD authentication are authenticated by the database and the user (OPS$LIVERPOOL\MARKWILL) with EXTERNAL is authenticated by Windows. That user shows up in the list in the Administration Assistant as expected.
Hopefully that makes a bit more sense now.
