Enterprise users can be authenticated using password authentication, SSL authentication, or Kerberos authentication. You can set the authentication modes that are allowed for an enterprise domain using Enterprise Manager. You can also enable current user database links for databases in the enterprise domain. These links enable databases to trust each other to authenticate users.
To configure user authentication types and enable current user database links:
Log in to Enterprise Manager Cloud Control, as an administrative user.
To navigate to your database, select Databases from the Targets menu.
Click the database name in the list that appears. The database page appears.
Under the Administration menu, select Security, Enterprise User Security. The Oracle Internet Directory Login page appears.
Enter the distinguished name (DN) of a directory user who can administer enterprise users in the User field. Enter the user password in the Password field. Click Login.
The Enterprise User Security page appears.
Click Manage Enterprise Domains.
The Manage Enterprise Domains page appears. This page lists the enterprise domains in the identity management realm.
Select the enterprise domain that you wish to configure. Click Configure.
The Configure Domain page appears.
Click the Configuration tab.
Under User Authentication Types Accepted, select the authentication types that you want to allow.
If you wish to enable current user database links for the domain, then select Enable Current User Database Links in this domain.
Click OK.
