We like to integrate the window LDAP to a new oracle database for user authentication. For example, this is a new test database and we don't have any users created.Now we like to figure out if we created the users with same id as in LDAP userid, how they can be authenticated externally by LDAP. I read and heard some info on OID provided by oracle but need some more step by step info to experiment.
View 3 RepliesI'd like to have my 11g database authenticate users against an OpenLDAP service. We'd still create accounts in the database, and do authorization within the database, but I'd just want to the user's passwords authenticated externally, against the OpenLDAP service. Is this possible? My searching through these forums and Google seems to indicate that you can do it if you run an Oracle Internet Directory (OID) service. I do not want to have to install and maintain an Oracle Internet Directory service. I'd like to do it without it.
I have a working PL/SQL function (below) that can authenticate a passed in username & password against our OpenLDAP directory. Is there any way for me to have Oracle call this function for the database user authentication? Or is there any other way for me to get the Oracle database to directly authenticate against OpenLDAP without having to run OID?
create or replace function ldap_authenticate(username varchar2, password varchar2)
return boolean is

I know how to use database links in various forms, but I've been trying to think through how the authentication works for a connected user link in 11g. If I create the link like this,create public database link using 'orcl';then any user can use the link, provided they have an identical username/password in the two databases. With pre-11g passwords, it was understandable: the password was salted with the username, so the hash of the password would be the same in both databases, and I assumed that the logon through the link used some sort of IDENTIFIED BY VALUES mechanism. But in 11g, the salt will different in the two databases. So the hash will be different. And of course Oracle never stores the actual password. So I don't see how the authentication works.

Why the Database is still looking for old AD user name? Does Oracle cache information about OS authenticated users?
I have got single sign on working via the built in LDAP Directory authentication in APEX. But at the moment this is letting everyone who is within AD log inHow can I assign role permissions to each logged in user so some users have an admin role and see certain parts of the application / pages / navigation items while editors and readers have different permissions
And also to restrict access to certain pages within the application

I have been using oracle based database security but company now wants to handle with windows authentication.I have windows os 2008 R2 and oracle 11.2.0.3.

I have oracle 10g up and running on Solaris 10, from windows I would like to connect to sql plus through windows authentication, for that I have already made sure that remote_auth = true and have created user in oracle with OPS$. But still I cannot connect.
I have the same setup but with oracle on windows server, the os authentication from windows clients works just fine.
does oracle 10g on solaris 10 supports windows os authentication?

View 1 Replies View RelatedWe are trying to implement the following security to our database.
As of now, the access rights are same for all the windows users logging into the Oracle application with the same Oracle user Id.
But now, we want to improve our security by granting different levels of rights to the users based on their Network Id even though they use the same Oracle User Id to log into the application.
We are not looking for the users to be identified externally.
(CREATE USER "OPS$ORACLE-BASE.COMTIM_HALL" IDENTIFIED EXTERNALLY;
GRANT CONNECT TO "OPS$ORACLE-BASE.COMTIM_HALL";

We have the database user called c88888 and is locked yesterday. I came to this with the following query.
select * from dba_users where username like 'C88888';
Due to invalid password the user was locked. Can we track who hit the database with the wrong password?
User A contains tables, views, LOB's, types, procedures, triggers, sequences, indexes, synonyms. User B wants to have read-only privilege on the objects of User A.
I can provide select on privilege on tables and views. How about providing read-only privileges to other objects?
I have enabled Auditing in my oracle Database but I am not able to see any database for the operations of sys user or any other user in my "SYS.AUD$" and "SYS.FGA_LOG$" tables.
Value for the parameter "AUDIT_TRAIL" is set to "db,extended".
I am working as "SYS" user and I have shutdown and again startup the database but neither there was any information in both the tables nor I can see any files at the destination specified by "AUDIT_FILE_DEST".
The following link states

SESSIONS_PER_USER
Each instance maintains its own SESSIONS_PER_USER count. If SESSIONS_PER_USER is set to 1 for a user, the user can log on to the database more than once as long as each connection is from a different instance.

Of course the following is not working even when resource_limit is TRUE

View 19 Replies View RelatedI am using Oracle Internet Directory to store user information and OID delegation administratibe services for user entry. An an admin I created a privileges group called admins. Users belonging to this group can create user, delete users, edit users, and edit groups. I created 'User A' and assigned him to the group. Now 'User A' creates 'User B' and assignes him to the group. However when 'User B' creates 'User C' he gets the error [LDAP: error code 50 - Insufficient Access Rights].
This happens even though 'User B' belongs to the admin group which has the privilege to create users.
The application user owns the application schema which owns all the database objects in this schema. Now 50 of our developers need access to this application schema but giving away the password for the application user is risk as "Drop user application cascade" and wipe off all the objects. The option i have is to create 50 separate users with tablespace as application and grant all rights to application schema.

I login as sysdba in sqlplus, created a user.
In the installation documentation it said :
This user should have at least the following privileges.
CREATE TABLE, CREATE VIEW, CREATE PROCEDURE, CREATE PUBLIC SYNONYM, CREATE USER, CREATE ROLE, CREATE SEQUENCE, CREATE SESSION CREATE TRIGGER, AND CREATE TYPE.
If you choose, you can grant DBA role to this user.
Note: Coeus Schema owner should have CREATE USER and ALTER USER right explicitly granted to it, not through a role like DBA.
