Db10g external password authentication with Active Directory via OID

HI ALL
- i have the synchronization AD-to-OID
- i have the external authorization of AD users via SSO (external authorization plug-in)
- i have the DB10g enterprise authorization of OID native users who have their password in OID (global schema)
- but i cann't configure the DB10g autorization of AD-to-OID synchronized users who don't have their password in OID
error:
ORA-28274: No ORACLE password attribute corresponding to user nickname exists.
i.e. those users are not recognized as users with external passwords.
Any ideas, please ...

Funny thing - LDAP (OID and Active Directory) defines a generic heirachical database. Like any other generic database, you need to define the schema to define what data is to be captured.
Each LDAP application expects a certain schema. That includes Enterprise User Security (part of the Advanced Security Option).
To accomplish what you want to do
1) get familiar with the Enterprise User Security capability (see the EUS documentation at tahiti)
2) learn to configure SQLNet / Oracle Networking to use LDAPthat is responsib (''cause it's Oracle Networking responsible for the login)
3) Reverse the schema from OID and transport it to AD
Aside from that, it's a no-brainer.

I've gone through that thread a few times already, but it only covers infrastructure based on Sun JDS, which seems to pose less problems than Active Directory. Many others refer only to hand-compiled OpenLDAP installations which are quite different to configure... sigh
I have, however, managed to get the base system running - meaning I can see Solaris ask LDAP for locally unknown user and group names - but all I get back is Unknown Object.
Here's a snoop dump of one of the failed requests, in hope someone here can shed some light on the problem:
request from my server to the LDAP box:

reply from the LDAP server:

LDAP: , problem 2001 (NO_OBJECT), data
a) our Active Directory 2003 R2 with the default Unix schema does not seem to implement the objectClass=posixAccount attribute, although the documentation on MSDN suggests that attribute should be there. I'm atm about to get some MS guy to solve this..
b) The base object DN seems to always get prefixed with ou=people - why? I didn't enter that field with ldapclient, and that orgunit does not exist in AD per default. How can I prevent Solaris from modifying my search path in that way? I think this is one of the reasons why I keep getting no-object-errors.
c) Our AD doesn't seem to offer a way to create/modify the unix object classes shadowExpire, shadowFlag and others for password management. Are those strictly necessary - i.e. will I run into new problems with those if I managed to solve a) and b)?

Oracle forms authentication with active directory without OID

Hi Gurus,
I need to implement active directory authentication in oracle forms.
My scenario is this:
1. The user is created in active directory
2. The user is imported in our aplication, and then I assign the roles in Oracle, and create the user in my aplicattion.
When the user logs, the system have to validate the password with MS-AD. If the password is right, then, the system start a session in Oracle.
My questions are:
1. How can I validate the password in AD ? Is it in clear text, unix crypt, AES ?
2. In case the user has changed the password in AD, how can obtain he logs in oracle with the new password ?
We use oracle enterprise edition, but we don't have oracle applications, so i can't use identity management.
Thanks in advance for your help

You will need Oracle SSO and OID to implement Active Directory authentication for Oracle Forms. It comes with Oracle Application Server. You will need to read up on how to use AD instead of OID as the user store for Oracle Single Sign-on (SSO). Forms will use SSO to login not really knowing which user store is used so there is no config needed on the Forms side (except enabling SSO).

ACS 5.3, EAP-TLS Machine Authentication with Active Directory

I have ACS 5.3. I am testing EAP-TLS Machine Authentication using Active Directory as an external Identity Store. II was testing and everything was going fine until I did some failure testing.
My problem: I deleted my computer account out of Active Directory and tried to authenticate my wireless laptop and it still worked when it should have failed.
Here is some of the output of the ACS log. You can see that the computer could not be found in AD and this was returned to the ACS. However, ACS still went ahead and authenticated the computer successfully.
Evaluating Identity Policy
15006 Matched Default Rule
22037 Authentication Passed

22064 New accounting session created in Session cache
11002 Returned RADIUS Access-Accept
I was assuming that if the computer was not found, the Identity Policy would fail, so I did not configure any authorization policy. Do I need an authorization policy to tell the ACS to fail the authentication if the machine cannot be found in AD? If I need an authorization policy, how do I configure it?
Note: In my Identity Store Sequence, I did enable the option:
For Attribute Retrieval only:
If internal user/host not found or disabled then exit sequence and treat as "User Not Found"
but this only seems to work for internal identity stores (at least based on my testing)
Under my Access Policy Identity tab, I configured the following Advanced features:
Advanced Options
If authentication failed
RejectDropContinue
If user not found
RejectDropContinue
If process failed
RejectDropContinue
And that didn't do anything either.
Any ideas? Thanks in advance.

Can try the following. Define an attribute to be retrieved from Active Directory and that exists for all objects. When defining the attribute it can be given a default value. Assign a default value which is a value that will never be returned for a real machine entry (eg "DEFAULTVALUE") and give it a "Policy Condition Name"
Then can make a rule in the authorization policy such as
If "Policy Condition Name" equals "DEFAULTVALUE" then "DenyAccess"

Problem authenticating with Active Directory

Hi,
We want to authenticate the users from Microsoft Active directory.We created users by doing a bootstrapping from AD to OID (10.1.2).
I enabled the plug in by following the Chapter 18 Configuring Active Directory External Authentication plug -in.
After running through the plug in is installed if i try to login with AD user id I am getting authentication failure error.
I am not sure whether OID is connecting to Active Directory for authentication.How to ensure that it is connecting to AD
I am giving uid attribute as login id.What is the login id to be given
I have tried many combinations no luck. I am getting following error in ssoServer.log

SAP R/3 Authentication with Active Directory on Win2k server.

Hello list ,
We are running SAP R/3 4.7 with WebAS 6.2 on Solaris and a Windows 2000 Active Directory domain. Our users access SAP in 3 ways
1) SAP GUI .
2) SAP BW
3) Travel & Expense - a java application that records users travel details and posts a transaction to SAP using the SAP userid and password.
Wish to implement SSO for all our users.
Some research we have done suggests
1) Using Kerberos for authentication. while it appears that microsoft krb 5 implementation will work only on windows servers, it is not clear how well are other krb implementations supported by SAP. OSS note # 150380 and link http://help.sap.com/saphelp_nw2004s/helpdata/en/44/0ebf6c9b2b0d1ae10000000a114a6b/content.htm
2) OSS note # 352295 suggest there could be some issue using KRB 5 shipped with unixes.
"All of the major Unix vendors seem to be shipping a version of Kerberos 5 these days. These implementations should be wire-interoperable with each other and with Microsoft W2K (not necessarily W2K3!), however they may not be interoperable with SAP's shared library interface to GSS-API v2 mechanisms."
3) There are some commercial solutions like - CyberSafe that provides krb based SSO at a fee. Has anyone tried this software ?
I have created an OSS ticket but we are still in a queue since 5 days already.
Has any one from the list implemented a similar solution ? What are the best practices and way to go for a robust solution.
4) Another option that we have is to start with user synchronization. Where in Users created in Active Directory get synchronized with SAP .
What is mandatory for us is that Users marked disabled in Active Directory should be blocked in SAP by synchronizing user information at regular interval. If anyone has implemented this solution I will appreciate if they give me some pointers.
Thanks in advance.

Tim,
you are perfectly right: that Vintela product is not certified (as SNC solution).
But you are not quite right regarding the separate treatment. The major difference between that product and the SNC certified products (such as CyberSafe, Entrust, ...) is: Vintela uses different SNC libraries on the client side (=> our Windows SSPI wrappers, see <a href="http://service.sap.com/~iron/fm/011000358700000431401997E/352295">SAP note 352295</a>) and the server side (=> their own SNC library, not certified). And that is actually also one reason why that solution cannot be certified ...
Well, those Windows SSPI wrappers provided by SAP (=> gsskrb5.dll, for example) are also not "SNC certified", but SAP provides support (being in contact with Microsoft). Well, as some people might know, there are also some interoperability issues between different Microsoft OS versions ... - resulting in reactive patches of our SSPI wrappers.
I really do <u>not</u> want to promote <u>any</u> product - neither the one of Quest Software Inc., nor the one of <a href="http://www.cybersafe.ltd.uk/">CyberSafe Ltd</a>, nor <a href="http://www.entrust.com">Entrust Inc.</a>, nor <a href="http://www.secude.com/">SECUDE IT Security GmbH</a>, nor ...
I do not even want to disencourage anyone from implementing his own Kerberos-based solution (or any other solution which provides an GSS API), provided that this person is able to help himself. Reason: if products of different vendors are used and interoperability problems occur the usual finger-pointing will start. In the end you'll not get support by anyone ... - as long as you are aware of this (and capable of helping yourself) you can go ahead. Some (known) universities are belonging to that group ... - but it might not be appropriete to the vast majority of customers.

i have tried to reconfig and reinstall the connector but still the same issue.

Don't think so.
Reconcile will just find accounts that are out of sync (that is, that exist on one system but not the other). It doesn't update account attributes.
ActiveSync can identify and process changed records, but the password itself is hashed, so unless you can use the hashed password directly (and IDM can't) then you just would get "garbage" data via the sync.
I think you do need to use one of the PasswordSync tools for this, because they intercept the password change process before the password is hashed, allowing you to apply the changes in multiple locations.

Kerberos authentication with Active Directory

I have tried using JAAS to authenticate to MS Active Directory and keep getting "javax.security.auth.login.LoginException: Pre-Authentication Information was invalid"
I have tried authenticating with multiple user accounts and on three different realms (Active Directory domains).
How do I need to format the username? I know that when using JNDI to access Active Directory I have to use the format "[email protected]" or the RDN. I have tried it both ways with JAAS kerberos authentication as well as with just the username by itself. I don't think that the username format is the problem though because if I set the account lockout policy to 5 failed attempts, sure enough my account will be locked out after running my code 5 times. If I give a username that doesn't exist in Active Directory I get the error "javax.security.auth.login.loginexception: Client not found in Kerberos database" Is there something special that I have to do to the password?
I know that there is just something stupid that I'm missing. Here is the simplest example of code that I'm working with:
import java.io.*;
import javax.security.auth.callback.*;
import javax.security.auth.login.*;
import javax.security.auth.Subject;
import com.sun.security.auth.callback.TextCallbackHandler;
public class krb5ADLogin1 {
public static void main(String[] args){
LoginContext lc = null;
try {
lc=new LoginContext("krb5ADLogin1", new TextCallbackHandler());
lc.login();
catch(Exception e){
e.printStackTrace();
Here is my config file:
krb5ADLogin1 {
com.sun.security.auth.module.Krb5LoginModule required;
The command I use to start the program is:
java -Djava.security.krb5.realm=mydomain.com
-Djava.security.krb5.kdc=DomainController.mydomain.com
-Djava.security.auth.login.config=sample.conf krb5ADLogin1

Hi there ... the Sun web site has the following snippet:
http://java.sun.com/j2se/1.4/docs/guide/security/jgss/tutorials/Troubleshooting.html
+ javax.security.auth.login.LoginException: KrbException::
Pre-authentication information was invalid (24) - Preauthentication failed
Cause 1: The password entered is incorrect.
Solution 1: Verify the password.
Cause 2: If you are using the keytab to get the key (e.g., by
setting the useKeyTab option to true in the Krb5LoginModule entry
in the JAAS login configuration file), then the key might have
changed since you updated the keytab.
Solution 2: Consult your Kerberos documentation to generate a new
keytab and use that keytab.
Cause 3: Clock skew - If the time on the KDC and on the client
differ significanlty (typically 5 minutes), this error can be
returned.
Solution 3: Synchronize the clocks (or have a system administrator
do so).
Good luck,
-Derek

Solaris authentication with Active Directory

Our shop is a mixed environment of Unix and Windows users. Many use both environments daily and there has been a desire to have a common authentication scheme. We have been able to successfully configure our RH Linux clients to authenticate against our Windows or NIS environment using pam and krb5, but have not been able to successfully adapt this to our Solaris (9/10) environment. Our Unix/Linux client environment is in a common NIS domain. We want to continue to use NIS for account management and add AD for authentication only i.e. if the username/password authenticates against AD or NIS, then the user login proceeds.
On Solaris I have been able to successfully configure the /etc/krb5/krb5.conf file so that a kinit can be done successfully. klist list out the info and kdestroy removes it. However, figuring out how to properly configure the /etc/pam.conf file to use this login/rlogin/ssh authentication is not making any progress. Various attempts to add the pam_krb5.so.1 plugin in various sections of the file have not worked. Can you advise me on the proper configuration for this to work and or the means to get it working?

Read up on Enterprise User Security (EUS), a feature of Oracle Enterprise Database.
Mark Wilcox also has several posts related to OVD/AD/EUS integration on his blog:

Authentication with Active Directory Group in WLS 10.0

Hi,
By using the Active Directory authenticator in WLS 10.0, I managed to get connected to the AD and can see the groups and users in the administration console.
But, I am having troubles setting up the security role(s) in my web app. I can't figure out how to configure it so that I can actually sign in to my web app using an AD group.
Here are the web.xml & weblogic.xml files:
web.xml
<web-app>
<welcome-file-list>
<welcome-file>/SecuredPage.jsp</welcome-file>
</welcome-file-list>
<security-constraint>
<display-name/>
<web-resource-collection>
</web-resource-collection>
<auth-constraint>
<description>Constraint for aduser</description>
<role-name>aduser</role-name>
</auth-constraint>
</security-constraint>

<login-config>
<auth-method>BASIC</auth-method>
<realm-name>myrealm</realm-name>
</login-config>

<security-role>
<description>Users of myADgroup</description>
<role-name>aduser</role-name>
</security-role>
</web-app>
weblogic.xml
<weblogic-web-app>
<security-role-assignment>
<role-name>aduser</role-name>
<principal-name>ADUserGroup</principal-name>
</security-role-assignment>
</weblogic-web-app>
For the above config, my intention is to give access only the members of ADUserGroup to my webapp. This group is listed in myrealm at WLS as well as members of this group (ADUserGroup). But while trying to login as any members of this group, got 403 error!
Any siggestion!!
Thanx in advance!
Any help would be appreciated!

Okay, guys, now it seems working as I changed group type from distrubtion to security in Active Directory.

Mac OSX Tiger Authentication with Active Directory

I'm at my wits end and need some help. We have a Windows network, that we joined a designers new Mac to. When he, or an administrator logs into the network from the Mac, when they try to access network shares, (GO-->Connect to Server) they get permission denied.
Any Ideas??
Thanks

Hi Daniel,
you can use the User Management Engine (UME) to do that. Just map your AD to UME (its done via xml-mapping file and pretty simple, although I dont have an example at hand).
You can then use the UME-API to check user Roles and Groups or access their attributes.

Oracle 9i/10G DB authentication using Active Directory (with out OID)

Hello All,
We want to use a Single-Password authentication scheme using the Active
Directory as the primary source for userId/Password.
We don't want to use the Active Directory and OID bridge.
As we have many databases and would like to configure all Databases to use Active
Directory for Authentication. Our goal is to have single id/password across all
the databases and any user should be able to login from any computer using their
windows id/password, note that we don't want to use the OSAuthentication.
We have read the documents provided by oracle for authentication using Active
Directory, we were able to create Oracle Schema in Active Directory and were
also able to register a DB with Active Directory and then created user as global
user in Oracle Database and provided the DN of the user. When we tried
authenticate with all this setup it comes back and says invalid ID/Password !!!
And with 10G database we get the Oracle Error ORA-03113: end-of-file on communication channel !!
Has any one tried or have information on Integrating Oracle to Auth against Active Directory?
Envoirnment:
Oracle DB Version: 9.2.0 and also tried on 10.0.1 with same results
Operating System: Windows 2000/ Windows 2000 Server
Constraint: We don't want to user OID ( as we don't have license for this
product ! )

I have a thread started similar to your request.
OS Authenication on Windows
Somewhere I read this. It works on Oracle 9i on Linux, but I have not tried it with Oracle 9i on Windows.
SHOW PARAMETER OS_AUTHENT_PREFIX;
SHOW PARAMETER REMOTE_OS_AUTHENT;
CREATE USER OPS$SOMEUSER IDENTIFIED EXTERNALLY;
GRANT CREATE SESSION TO OPS$SOMEUSER;
For the username, I wonder if we are supposed to put the Windows Domain name as part of the username? Such as, for a Windows domain user MyDomain\SomeUser
CREATE USER OPS$MYDOMAIN\SOMEUSER IDENTIFIED EXTERNALLY;
I really wish Oracle or somebody created a guide or book on how to do this.

Sync external database with Active Directory

Hi,
We are in the process of consolitating all user information in our systems in Active Directory.
We have a system that can only authenicate users from information stored in a relational database. We are investigating options that would allow us to sync the password in this relational database with the password stored in Active Directory. Whenever the user changes their domain password, we would like for an JNDI application to update the relational database with their new password.
I'm fairly new to JNDI/Active Directory. My research does not look too positive. Does anybody know of any way that we can perform this password synchronization? Any advice would be greatly appreciated!
Thanks!

There are several mechanisms available that enable AD to authenticate users for your web application.
1. Perform a simple LDAP bind using the user's credentials submitted from a form. If the bind is successful, then you can infer that the credentials are correct.
2. If the users have already performed an interactive logon to Active Directory, provide a Single Sign-On experience by utilizing their existing Kerberos ticket. Refer to JNDI, Active Directory and Authentication (Part 1) (Kerberos)
http://forum.java.sun.com/thread.jspa?threadID=579829&tstart=300
for an explanation of using Kerberos & GSS-API.
3. If the users are not performing an interactive logon to your Active Directory, but you want to provide a federated single sign-on experience, then you may be interested in Active Directory Federation Services which uses SAML 1.0 tokens & WS-* to assert claims. Information on ADFS can be found at http://www.microsoft.com/windowsserver2003/techinfo/overview/adfsoverview.mspx
Two third party ISV's; Vintela and Centrify both provide solutions for non-Windows Web Servers to enable the second & third scenarios.
