Users with Non-ASCII Names Might Encounter Problems when Using ODSM with SSO
When you create an Oracle LDAP listener in Enterprise Manager, and then edit the listener's Change SSL setting by selecting Enable SSL for any SSL authorization, Enterprise Manager selects the ciphersuite TLS_DHE_RSA_WITH_AES_128_CBC_SHA256. If this ciphersuite is selected, then Oracle Virtual Directory will fail to start-up entirely.
Oracle Virtual Directory supports the following protocols:
TLSv1
SSLv2Hello
SSLv3
Note:
For a complete list of the supported ciphers for each protocol, refer to the following location:
To work around this issue, manually uncheck all of the ciphers listed for Enterprise Manager when configuring the ciphersuites.
When creating an EUS adapter using the wizard in ODSM, an error message periodically displays stating the adapters and ACLs were not created successfully.
To work around this issue, proceed as follows:
If the error occurred while you were loading ACLs, and only partial ACLs were loaded during EUS configuration, then you can manually load the remaining ACLs by running this command:
$ORACLE_HOME/bin/ldapmodify -c -v -h <ovd_host> -p <ovd_port> -D cn=orcladmin -w <orcladmin_password> -f $ORACLE_HOME/ovd/eus/eusACLTemplate.ldif
If the error occurred during any other step, then manually clean up the partial configuration from Oracle Virtual Directory by using the following steps, and then reconfigure Oracle Virtual Directory for EUS.
Delete all of the Local Store and LDAP EUS adapters created.
Delete the LSA EUS adapter data files from the local file system.
Undeploy the EUS py mapping based on your directory type (if it exists).
Click the EUS wizard icon again to reconfigure.
Creating a Database Adapter with Sybase as back-end causes Oracle Virtual Directory to fail with an Invalid Database Connection error.
To work around this issue, you can manually edit the adapters.os_xml file using the same Database connection information.
The Oracle Directory Services Manager version shown in Enterprise Manager is the application version, which does not change when you patch ODSM.
The Oracle Lifecycle team requires all Enterprise Manager components to retain the same application version. However, because customers want to know which ODSM version they are using, ODSM maintains the actual (patch) version and Enterprise Manager maintains the application version, which causes this mismatch.
This issue is a known issue, starting with version 11.1.1.3.0.
Due to a misplaced comment in the file odsmSkin.css, some labels on the ODSM home page are not displayed correctly. Specifically, the labels in the diagram on the right are misplaced or missing.
To work around this issue, proceed as follows:
Stop the wls_ods1 managed server and the WebLogic Administration server.
Edit the file:
MW_HOME/user_projects/domains/DOMAIN_HOME/servers/MANAGED_SERVER_NAME/tmp/_WL_user/ODSM_VERSION_NUMBER/RANDOM_CHARACTERS/war/skins/odsmSkin.css
For example:
wlshome/user_projects/domains/base_domain/servers/wls_ods1/tmp/_WL_user/odsm_11.1.1.2.0/z5xils/war/skins/odsmSkin.css
Before editing, the odsmSkin.css file looks like this:
@agent ie /*========== Fix for bug#7456880 ==========*/
{
af|commandImageLink::image,
af|commandImageLink::image-hover,
af|commandImageLink::image-depressed
{
vertical-align:bottom;
}
}
Move the comment:
/*========== Fix for bug#7456880 ==========*/
so that it is above the line
@agent ie
After editing, the file should look like this:
/*========== Fix for bug#7456880 ==========*/
@agent ie
{
af|commandImageLink::image,
af|commandImageLink::image-hover,
af|commandImageLink::image-depressed
{
vertical-align:bottom;
}
}
Restart the WebLogic Administration server and the wls_ods1 managed server.
In some circumstances, after you launch Oracle Directory Services Manager from Fusion Middleware Control, then select a new Oracle Directory Services Manager task, the browser window might become unusable. For example, the window might refresh repeatedly, appear as a blank page, fail to accept user input, or display a null pointer error.
As a work around, go to the URL: http://host:port/odsm, where host and port specify the location where Oracle Directory Services Manager is running, for example, http://myserver.example.com:7005/odsm. You can then use the Oracle Directory Services Manager window to log in to a server.
Under certain circumstances, when managing multiple Oracle Virtual Directory components from the same Oracle Directory Services Manager session, exception or error messages may appear if you stop one of the Oracle Virtual Directory components. For example, you are managing Oracle Virtual Directory components named ovd1 and ovd2 from the same Oracle Directory Services Manager session. Both ovd1 and ovd2 are configured and running. If you stop ovd1, an exception or Target Unreachable message may appear when you try to navigate Oracle Directory Services Manager.
To work around this issue, exit the current Oracle Directory Services Manager session, close the web browser, and then reconnect to Oracle Virtual Directory components in a new Oracle Directory Services Manager session.
When you create an Access Control Point (ACP) using Oracle Directory Services Manager, the Relative Distinguished Name (RDN) of the DN where you created the ACP appears in the navigation tree on the left side of the screen. For example, if you create an ACP at the DN of cn=ForExample,dc=us,dc=sales,dc=west, then cn=ForExample appears in the navigation tree. After clicking an ACP in the navigation tree, its settings appear in the right side of the screen and the RDN it is associated with appears at the top of the page.
To identify the DN associated with an ACP, move the cursor over ("mouse-over") the ACP entry in the navigation tree. The full DN associated with the ACP will be displayed in a tool-tip dialog box.
Mousing-over ACPs in the navigation tree is useful when you have multiple ACPs associated with DNs that have identical RDNs, such as:
ACP 1 = cn=ForExample,dc=us,dc=sales,dc=west
ACP 2 = cn=ForExample,dc=us,dc=sales,dc=east
This topic describes issues with Oracle Virtual Directory metrics in Fusion Middleware Control, including:
If you upgraded an Oracle Virtual Directory Release 10g installation with plug-ins configured to execute on specific operations, such as add, bind, get, and so on, to 11g Release 1 (11.1.1), you may have to update those operation-specific plug-ins before you can use Fusion Middleware Control to view performance metrics.
After upgrading to 11g Release 1 (11.1.1) and performing some initial operations to verify the upgrade was successful, check the Oracle Virtual Directory home page in Fusion Middleware Control. You should see data for the Current Load and Average Response Time and Operations metrics.
If you do not see any data for these metrics, you must update the plug-ins configured to execute on specific operations. The work-around is to add the Performance Monitor plug-in to the operation-specific plug-in's configuration chain.
Perform the following steps to add the Performance Monitor plug-in to the operation-specific plug-in's configuration chain:
If the operation-specific plug-in is a Global-level plug-in, edit the server.os_xml file located in the ORACLE_INSTANCE/config/OVD/NAME_OF_OVD_COMPONENT/ directory.
If the operation-specific plug-in is an adapter-level plug-in, edit the adapters.os_xml file located in the ORACLE_INSTANCE/config/OVD/NAME_OF_OVD_COMPONENT/ directory.
Locate the pluginChains element in the file. For example, if the Dump Transactions plug-in is configured to execute on the get operation, you will see something similar to the following:
Example 28-1 Dump Transactions Plug-In Configured for get Operation
<pluginChains xmlns="http://xmlns.oracle.com/iam/management/ovd/config/plugins"> <plugins> <plugin> <name>Dump Transactions</name> <class>com.octetstring.vde.chain.plugins.DumpTransactions.DumpTransactions</class> <initParams> <param name="loglevel" value="info"/> </initParams> </plugin> <plugin> <name>Performance Monitor</name> <class>com.octetstring.vde.chain.plugins.performance.MonitorPerformance</class> <initParams/> </plugin> </plugins> <default> <plugin name="Performance Monitor"/> </default> <get> <plugin name="Dump Transactions"> <namespace>ou=DB,dc=oracle,dc=com </namespace> </plugin> </get> </pluginChains>
Add the following Performance Monitor plug-in element within the operation-specific configuration chain:
<plugin name="Performance Monitor"/>
For example:
Example 28-2 Adding the Performance Monitor to the Operation-Specific Plug-In Configuration Chain
<pluginChains xmlns="http://xmlns.oracle.com/iam/management/ovd/config/plugins">
<plugins>
<plugin>
<name>Dump Transactions</name>
<class>com.octetstring.vde.chain.plugins.DumpTransactions.DumpTransactions</class>
<initParams>
<param name="loglevel" value="info"/>
</initParams>
</plugin>
<plugin>
<name>Performance Monitor</name>
<class>com.octetstring.vde.chain.plugins.performance.MonitorPerformance</class>
<initParams/>
</plugin>
</plugins>
<default>
<plugin name="Performance Monitor"/>
</default>
<get>
<plugin name="Dump Transactions">
<namespace>ou=DB,dc=oracle,dc=com </namespace>
</plugin>
<plugin name="Performance Monitor"/>
</get>
</pluginChains>
Save the file.
Restart Oracle Virtual Directory.
Currently, a TimesTen bug is preventing wildcard searches (such as "cn=t*") from working in a Database adapter with TimesTen.
To work around this problem, enable the Case Insensitive Search option and create the necessary linguistic indexes for any database columns used in the search.
For more information, see the related TimesTen Enhancement Request, Bug# 9885055 and Section 12.2.2 "Creating Database Adapters for Oracle TimesTen In-Memory Database" in the Oracle® Fusion Middleware Administrator's Guide for Oracle Virtual Directory.
Oracle Directory Services Manager Version 11.1.1.4.0 does not support Oracle Virtual Directory Versions 11.1.1.2.0 or 11.1.1.3.0.
Changes introduced in Oracle Directory Services Manager Version 11.1.1.4.0 improve configuration auditing, and these changes require that you use Oracle Virtual Directory 11.1.1.4.0.
Oracle Directory Services Manager Version 11.1.1.5.0 does not support Oracle Virtual Directory Versions 11.1.1.2.0, 11.1.1.3.0, or 11.1.1.4.0.
Changes introduced in Oracle Directory Services Manager Version 11.1.1.5.0 improve configuration auditing, and these changes require that you use Oracle Virtual Directory 11.1.1.5.0.
Oracle Directory Services Manager Version 11.1.1.6.0 does not support Oracle Virtual Directory Versions 11.1.1.1.0, 11.1.1.2.0, 11.1.1.3.0, 11.1.1.4.0, or 11.1.15.0.
Changes introduced in Oracle Directory Services Manager Version 11.1.1.6.0 improve configuration auditing, and these changes require that you use Oracle Virtual Directory 11.1.1.6.0.
When ODSM is configured to use Oracle Access Manager 11g Release 1 (11.1.1.2) for single sign-on, a user whose name contains non-ASCII characters might observe the following issues after logging in:
The user name displayed on the Home page is garbled.
Single sign-on connections to Oracle Virtual Directory servers do not appear in the list of connections.
After upgrading Oracle Directory Services Manager, creating an attribute or an objectclass causes an NPE error.
Workaround:
Refresh the entries by clicking Refresh every time the creation fails.
An additional Patch 10365116 is required to enable the Account Lockout functionality.
In addition, Oracle Virtual Directory may not update the AD badpasswdcount until the account is fully locked out, which means AD badpasswdcount shows the correct number when it reaches the bad password count setting in AD.
The ODSM interface might not appear as described in Internet Explorer 7.
For example, the Logout link might not be displayed.
If this causes problems, upgrade to Internet Explorer 8 or 9 or use a different browser.
This section describes a configuration issue and its workaround. It includes the following topic:
For certain operations, the out-of-box heap size of 512 MB is not sufficient for Oracle Virtual Directory (OVD) on AIX.
Increase the heap size to over 1 GB for production environments. Complete the following steps to increase the heap size for Oracle Virtual Directory (OVD):
In INSTANCE_HOME/config/OPMN/opmn.xml, find the following XML fragment:
<process-type id="OVD" module-id="OVD">
<environment>
<variable id="TNS_ADMIN" value="$ORACLE_INSTANCE/config"/>
</environment>
<module-data>
<category id="start-options">
<data id="java-bin" value="$ORACLE_HOME/jdk/bin/java"/>
<data id="java-options" value="-server -Xms512m -Xmx512m
-Dvde.soTimeoutBackend=0
-Doracle.security.jps.config=$ORACLE_INSTANCE/config/JPS/jps-config-jse.xml"/>
<data id="java-classpath"
value="$ORACLE_HOME/ovd/jlib/vde.jar$:$ORACLE_HOME/jdbc/lib/ojdbc6.jar"/>
</category>
</module-data>
<stop timeout="120"/>
</process-type>
Modify the default -Xmx512m to an appropriate value. For example: -Xmx2048m.
Shutdown Oracle Virtual Directory.
Execute opmnctl reload command to refresh OPMN configuration.
Start Oracle Virtual Directory.
This section describes documentation errata in the Administrator's Guide for Oracle Virtual Directory. It includes the following topics:
Description of filterObjectClassOnModify Parameter is Incorrect
Deploying Oracle Unified Directory with Oracle Virtual Directory
The GroupURL attribute that is described in section 11.5.1.1, "Configuring Admin Listener Settings Using WLST" of the Oracle® Fusion Middleware Administrator's Guide for Oracle Virtual Directory was documented using the wrong case. This attribute should be GroupUrl, where only the "G" and the "U" are in uppercase letters.
The description provided for the filterObjectClassOnModify parameter in the Oracle® Fusion Middleware Administrator's Guide for Oracle Virtual Directory states that it is a comma-separated list of attributes that are removed during the modify operation for a specific objectclass. This description should read as follows:
Use the filterObjectClassOnModify parameter to remove objectClass entry changes on modify operations. Supported values include true (remove changes) and false (do not remove changes). Where true is the default. For example:
Parameter Name: filterObjectClassOnModify
Parameter Value: true, false
You can deploy Oracle Unified Directory as an LDAP data source with Oracle Virtual Directory. For information about how to deploy Oracle Unified Directory with Oracle Virtual Directory, see "Creating LDAP Adapters" in the Oracle® Fusion Middleware Administrator's Guide for Oracle Virtual Directory.
The code example currently provided in section 18.3.3.3, "Operation Plug-In Implementation Point" of the Oracle® Fusion Middleware Administrator's Guide for Oracle Virtual Directory does not close the connection to the back-end LDAP server.
The example code uses chain.getVSI().get, which populates a Vector<EntrySet> with one EntrySet for each adapter. Each EntrySet in get() contains a live handle to the data source connection, which is used to retrieve entries.
To release this data source connection to the pool, you must provide a call to EntrySet.cancelEntrySet()or Oracle Virtual Directory could be blocked. Blocking occurs when the plug-in occupies all of the configured connections from the pool and no connections are available to execute new requests.
The example code should be updated to implement a call to entrySet.cancelEntrySet() as follows:
ChainVector results = new ChainVector();
try
{
chain.getVSI().get(...);
}
catch (...)
{
}
finally
{
for (EntrySet entrySet : results)
entrySet.cancelEntrySet();
}
Section 19.2.3.3.1, "Configuring Oracle Virtual Directory for the Integration" in the Oracle® Fusion Middleware Administrator's Guide for Oracle Virtual Directory should include an instruction for setting SSL Authentication Mode. The section should read as follows:
Select the EUS_Sun template.
Set SSL Authentication Mode to Server Only / Mutual Authentication.
The Proxy DN user must be able to read the userPassword attribute in the Oracle Directory Server Enterprise Edition.
