can someone please tell the difference between Oracle Internet Directory and Oracle Access Manager?
For Single sign on configuration do we need both?
thanks

yes both needs to be present.
Oracle Internet Directory is LDAP Server. OID (Oracle Internet Directory ) from OAM perspective contains the user's data. OAM uses OID as user identity store. But OID is not mandatory, any other LDAP server can be used like AD, DSEE, OVD, OUD.
OAM provides authentication, authorization, single sign on and session management service for web applications (It also supports same for non-web based application).

We are in the planning phase of configuring our soon-to-be-upgraded databases (19c) to authenticate directly against AD (no oracle proxy). I have read a handful of documents from Oracle on how to do this. Most of the documentation focuses around using passwords (password filter/verifier). The only problem is that our AD administrators are dead-set against implementing Oracle's password filter into our existing AD infrastructure. That being said, one of the security guys said we could implement the oracle authentication using Kerberos instead. From what I have read, and the documents are scattered all over the place, and nothing that detailed, to use Kerberos:
1) The client no longer uses a username/password - they connect using a wallet-style connection (e.g. /#dbname)
2) Not only does the Oracle DB need some configuration changes, but so does every client that plans on using Kerberos
I don't know anything about Kerberos, how it works, and what goes on when you implement this, but I was hoping for, at the end of this is:
1) No client changes/installs (only the oracle DB would have config changes)
The user will continue to provide credentials as before - completely transparent
2) No need for the password filter as our admins have a "beef" against it
So my question is:
If using Kerberos directly against AD on >=18c:
1) Does the client user still provide a username and password to authenticate against AD, or does the client simply get "accepted" due to the tickets/tokens/configuration that occurs on the client (i.e. the client is simply trusted)?
2) Is there client config changes that need to occur, or does the client reach out to the DB and the DB, with its config changes, does all the legwork to authenticate against AD based off of client info being passed
3) Does any additional manual component need to occur on occasion (periodically retrieving a ticket/token/something) (because, say, it expires)
So in the end, we want to have complete transparency with every client and using something other than the password verifier with AD.
Thanks in advance.

It sounds like you want to authenticate Windows clients against an Oracle database over a network using Active Directory without making any client changes.
This is pretty open-ended and complex StackOverflow question.
Probably you've been reading the docs about Third Party Network Authentication using Oracle Advanced Security. You can use Kerberos, SSL, RADIUS, PKI, etc. For most of these options, you need to do some setup on the client, because both the Oracle client and server need to authenticate or verify with the third-party system.
I think you need Enterprise User Security (using Oracle Internet Directory). Assuming you go with password-based authentication, you don't need client changes. In this scenario, Oracle Internet Directory can synchronize its user directory with AD, so your users can use their same username/password. However, when they change their AD password, they'll need to change their Oracle password separately.
On a different note, you may be able to alleviate your AD admins' fears about Oracle password complexity requirements, since you can change or remove those to fit your AD requirements.
I have got the following Article from Microsoft
For the Windows Server Technical Preview, the AD FS server role includes the same functionality and feature set that is available in Windows Server 2012 and Windows Server 2012 R2. It also includes new features that enable you to configure AD FS to authenticate users stored in non-AD directories, such as X.500 compliant Lightweight Directory Access Protocol (LDAP) directories and SQL databases. In many organizations, identity management solutions consist of a combination of Active Directory, AD LDS and third-party LDAP directories, as well as SQL databases. With the AD FS support of the non-AD identity stores, you can benefit from the entire enterprise-ready AD FS feature set regardless of where your user identities are stored. For more information, see Configure AD FS to authenticate users stored in LDAP directories
My question is how can I create custom authentication stores in SQL DB?
You are asking about ADFS 3.0 but the quote refers to ADFS vNext?
If the question is "Does ADFS3.0 provide custom authentication stores in SQL DB", the answer in No.
ADFS 3.0 only authenticates against AD.
I am trying to setup Kerberos authentication for my Oracle database and I have a situation where I need to maintain different versions of sqlnet.ora for each kerberos user connection. My application is using OCI driver (a single unix process does more than one user connection to the same Oracle database). And I am not able switch sqlnet.ora between user connections using setenv(TNS_ADMIN) call programmatically. I am assuming once the contents of sqlnet.ora gets loaded to process, it remains unchanged for the rest of its life.
Is my case a practical one, has anyone encountered?
When it comes to kerberos, I am not sure why Oracle client restricts the sqlnet.ora to one principal kerberos user. Maybe Oracle does not have a clean support for kerberos as I dont see OCI API's?
Thanks

When configuring the global security for Websphere Application Server, no matter you choose Federated Repositories, LDAP registry or custom registry, there is a property named 'Server user identity' to be setup. According to the official explanation, this is used for authentication during server to server communication. Does it mean when server communicating with each other within one cell, authentication is required and this value would be used there? And does this value only impact internal process, like within same cell? Or it can also be between cells? If it's not leveraged like this way, then how does 'Server user identity' work?
Kinda don't understand this. Please help me figure it out. Thanks in advance
Until WAS 6, a single user identity was required, namely 'primary administrative user', for both administrative access and internal process communication . This user, by definition, had to exist on the configured user registry.
From version 6.1 onwards, WAS requires an administrative user, distinguished from the server user identity, so that administrative actions can be audited separately.
For all practical purposes, if you are using version 6.1+, and you are not in a mixed-release cell (cell containing profiles of older versions of WAS in addition to current versions), you may just go ahead with automatically generated internal user id. An internally-generated server ID also adds a further level of protection to the server environment because the server password is not exposed.
For mixed-release cells you may check infocenter here for details on how to configure server user id in this case.
Server user id is used for server to server communication in a cell. I could not find any documentation that implies this parameter is also related with cross cell communication.
We are trying to shape up an old, 2 tier, Delphi based application. It originally uses database authentication, we'd like to transform the db user accounts to global users, so an OID server could perform the authentication instead of the database.
The Delphi program can no longer log into the database if the account is a global user. I'm trying to understand the login protocol, so far without results.
Similar thing happens with SQLDeveloper, I can't connect as a global user. SQLPlus however works with both kinds of users. We checked the information flow with Wireshark. When the dbserver asks back for a password, the SQLPlus sends it, while the SQLDeveloper doesn't send a password when attempting to connect as a global user.
The client sends the application name too in the login request. Is it possible that we have to store the client app name in the LDAP itself?
To connect to Oracle using OID, application must properly configure OCI (Oracle Call Interface). The data access components (which one ?), you are using, must set OCI_ATTR_DISTINGUISHED_NAME session attribute. If that is not done, then you will be not able to connect to Oracle server using ODI and OCI.
You should check your components documentation for this feature. And if it is not implemented, then discuss this issue with the components vendor. Actually, there is not much work to implement, but some work to setup testing environment is required ...
