Steps to create partitions in WLS 12.2.1

Below are the steps to create partitions in Weblogic Server 12.2.1 :

Step 1 :

- Create a weblogic domain (say Partition_From_Windows_Domain)

FMW control is the recommended console for Partition management, so it is good to enable it at the time of  domain creation.  

To enable FMW control select "Oracle Enterprise Manager-Restricted JRF - 12.2.1 [em]" template in the configuration wizard, as shown below :

To access FMW control access : http://<host>:<port>/em

NOTE : We will continue using Weblogic Admin console to create partitions in this example.

Partition names : coke-partition and pepsi-partition

Partition specific realms : coke_realm and pepsi_realm

Partition specific Admin Users : coke_admin and pepsi_admin

Virtual Targets for these partitions : coke-vt and pepsi-vt

Partition Specific Resource Groups : coke-rg1 and pepsi-rg1

Step 2 :

Before creating a partition, you need to create a security realm (then create an Admin user inside this realm, say coke_admin and pepsi_admin) and virtual target for this partition :

To create a new security realm :

Login to console -> Security Realms -> new (say 'coke_realm' and 'pepsi_realm') -> "create default providers within this new realm" (check)

Now create a Virtual target :

Login to console -> + Environment -> Virtual Targets -> new (say coke-vt) and target it to Weblogic Server (say Admin Server) -> specify a URI Prefix

Step 3 :

Lets create a partition now :

Login to console -> Domain Partitions -> new (say coke-partition)-> then target it to a Virtual target (say coke-vt) -> select the security realm for this partition from the drop down menu (say coke_realm)

 Step 4 :

Create a Resource Group inside domain partition


 Step 5 : 

Check the Identity Domains of the partitions :

Step 6 :

You can now deploy applications to Global scope / to a resource group of a partition

To access the application deployed to your partition use the following URL :

http://<host>:<port>/coke/Weblogic_SP_sample_App/login.jsp  ==> Try to login with the coke Admin and also test the login using weblogic user.

Perform similar tests with application deployed on pepsi-partition and global scoped deployment.

How to store database credentials in Oracle Wallet (for WLS datasource definitions)

Oracle Wallet provides an simple and easy method to manage database credentials across multiple domains. It allows you to update database credentials by updating the Wallet instead of having to change individual data source definitions.

This is accomplished by using a database connection string in the data source definition that is resolved by an entry in the wallet.

The wallet can be used to have common credentials between different domains. That includes two different WebLogic Server domains or sharing credentials between WebLogic Server and the database. When used correctly, it makes having passwords in the data source configuration unnecessary.

In this post we will see, how to create a datasource which uses the database credentials stored in a wallet to connect to a database.....

Steps to configure SAML SSO with ADFS (as IDP) and Weblogic Server (as SP)

Active Directory Federation Services (ADFS) is a software component developed by Microsoft that can be installed on Windows Server operating systems to provide users with single sign-on access to systems and applications located across organizational boundaries.

In this example we are using ADFS 2.0 on Windows Server 2008 R2.

ADFS 2.1 is available on Windows 2012 and ADFS 3.0 on Windows 2012 R2.

AlternateLoginID feature is introduced in Windows Server 2012 R2.

You can download ADFS from the following link : 

Link : http://www.microsoft.com/en-us/download/details.aspx?id=10909  --> " RTW\W2K8R2\amd64\AdfsSetup.exe " for Windows Server 2008 R2.

In this post we will see how to configure Single sign-on (SSO) using SAML where ADFS is used as Identity Provider and Weblogic is used as a Service Provider.

X509 Certificate Revocation Checking using OCSP (Online Certificate Status Protocol) in Weblogic Server

The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate.

It was created as an alternative to certificate revocation lists (CRL)

When you enable Certificate Revocation Checking in Weblogic, you can select the order for Revocation checks.

Default Behavior is to check the certificate's revocation status using OCSP and if it returns "unknown" then do a CRL check.

Optionally you can force Weblogic to do only OCSP check, only CRL check OR CRL then OCSP check.

By default if the certificate's revocation status cannot be determined then the certificate is accepted. If you want to change this behavior then select "Fail On Unknown Revocation Status" check-box in WLS console.

In this post we will see how to configure OCSP in Weblogic and demonstrate Certificate revocation checking...

Steps to configure Kerberos / SPNEGO / NTLM authentication with Weblogic Server running on IBM JDK (AIX machine)

There are many JAAS parameters deprecated in different IBM JDK versions.

Have a look at the following link which has more information about the same :

Link : http://www-01.ibm.com/support/knowledgecenter/SSYKE2_7.0.0/com.ibm.java.security.component.70.doc/security-component/jgssDocs/jaas_login_user.html

The searching sequence for a default keytab would be:

1, System property or system environment KRB5_KTNAME.

2, The value of default_keytab_name in libdefaults section in krb5.conf file.

3, if user.home is defined, look for user.home/krb5.keytab

4, if user.dir is defined, look for user.dir/krb5.keytab

5, otherwise, use /krb5.keytab

Have a look at the following link to configure Kerberos with Weblogic Server running on Oracle JDK :

How to configure a Custom IDP login page for SAML SSO in Weblogic

In case of an IDP initiated SSO, you can either get an initial challenge from the browser or you can customize it by using a FORM login by changing the <auth-method> in the web.xml file of your SourceApplication.

However, if you are doing a SP initiated SSO, then the challenge you get from IDP is always a BASIC challenge from browser.

How do you customize this ?

Can you create a custom login page ?

Steps to create a .jks keystore from .pfx file

What are the different certificate extensions ?

How do they differ from each other ?

Common filename extensions for X.509 certificates are:

.pem – (Privacy-enhanced Electronic Mail) Base64 encoded DER certificate, enclosed between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----"

.cer, .crt, .der – usually in binary DER form, but Base64-encoded certificates are common too.

If you have a .pem file (Base64) then you can directly rename the file to .cer / .crt and open the certificate in Windows to view its contents. ( by double clicking on the file ) 

.p7b, .p7c – PKCS#7 SignedData structure without data, just certificate(s) or CRL(s)

.p12 – PKCS#12, may contain certificate(s) (public) and private keys (password protected)

.pfx – PFX, predecessor of PKCS#12 (usually contains data in PKCS#12 format, e.g., with PFX files generated in IIS)

PKCS#7 is a standard for signing or encrypting (officially called "enveloping") data. Since the certificate is needed to verify signed data, it is possible to include them in the SignedData structure. A .P7C file is a degenerated SignedData structure, without any data to sign.

PKCS#12 evolved from the personal information exchange (PFX) standard and is used to exchange public and private objects in a single file.

Steps to configure Custom Identity and Custom Trust with Weblogic Server

What are the different ways keystore can be configured with Weblogic Server ?

What is the default keystore configuration in Weblogic ? 

Weblogic is configured with DemoIdentity and DemoTrust by default.

If you have generated any of the following certficate / keystores then you need to configure a CustomIdentity and CustomTrust as shown in this blog post :

 - Self signed certificate / keystore

- Generated a csr and got a certificate signed from a 3rd party Certificate Signing Authority ( CA ) 

- Generated a csr and got the certificate signed by an internal CA.

 You can also configure a Custom Identity and Java Standard Trust when you have any of the above certificates.

 In case of CustomIdentity and JavaStandardTrust, we create a Identity keystore and for the Trust keystore we make use of the default JDK Trust store i.e cacerts.

We need to import the root/intermediate certificate to cacerts using the following command :

keytool -import -file <root_certificate> -keystore <JDK>/lib/security/cacerts -storepass changeit 

In this post we will see how to configure a Custom Identity and Custom Trust with Weblogic Server.........

Steps to configure SAML 2.0 with Shibboleth ( deployed on WLS ) as IDP and Weblogic as SP.

Shibboleth is a free and open source federated identity solutions.

Points to Remember:

The logging configuration for the IdP is located at $IDP_HOME/conf/logging.xml. This file is checked for changes every 10 minutes  by default and is reloaded if changes have been made. 
This means a deployer can keep the logging level at WARN until a problem occurs and then change the logging to DEBUG to get more information if the problem persists, all without restarting the IdP.

By default Shibboleth 2.0 Identity Providers write to three log files :

- idp-access.log contains a log entry for each time the IdP is accessed, whether information was ever sent back or not. These messages include request time, remote host making the request, server host name and port, and the request path. This log is written in the machine parsable format requestTime|remoteHost|serverHost|serverPort|requestPath|.

- idp-audit.log contains a log entry for each time the IdP sends data to a relying party. These messages include the audit event time, IdP and relying party IDs, request and response binding, communication profile ID, request and response ID, principal name, authentication method, and released attribute of the current user. This log is written in the machine parsable format auditEventTime|requestBinding|requestId|relyingPartyId|messageProfileId|assertingPartyId|responseBinding|responseId|principalName|authNMethod|releasedAttributeId1,releasedAttributeId2,|nameIdentifier|assertion1ID,assertion2ID,|
Note the name identifier and assertion IDs were added in V2.1.

- idp-process.log contains messages logged during the normal operation of the IdP. This log is meant to be human readable and contains messages that indicate what the IdP is currently doing, encountered errors, warning messages that may indicate potential problems, etc.

All logging messages are "rolled over" at midnight each night, if the IdP is running, or the next time the IdP starts up after that.

You can test your configuration here :

http://www.testshib.org/

Here are few other sites which might be helpful :

https://sp.testshib.org/

https://shibboleth.usc.edu/docs/sp/install/

NOTE :

SAML2 Assertions encryption is a feature that is not supported by any current version of WebLogic Server, whatever the Identity Provider.

SAML2 Assertions in WebLogic Server are base64 encoded but not encrypted.

In the case of Shibboleth Identity Provider, the default Out-Of-The-Box configuration is to require encryption of the SAML2 Assertions. Thus, this issue is usually raised when using Shibboleth as the Identity Provider.

Shibboleth can be configured to use non-encrypted SAML2 Assertions, for instance check this :

Link : https://wiki.shibboleth.net/confluence/display/SHIB2/IdPXMLSigEnc

The wiki describes the way to configure Shibboleth when used in conjunction with WebLogic Server.

In this post we will see how to configure SAML 2.0 SSO using Shibboleth as IDP ( deployed on WLS ) and Weblogic as SP...

Steps to create a csr ( certificate signing request ) using keytool and get it signed from an external CA ( Certificate Authority - Thawte )

How to create a csr ?

How to get a certificate signed from an external / third party CA ?

How to create a certificate chain ?

-----------

 Defaults for keytool command in Java 1.6 :

-alias "mykey"

-keyalg

    "DSA" (when using -genkeypair)

    "DES" (when using -genseckey)

-keysize

    1024 (when using -genkeypair)

    56 (when using -genseckey and -keyalg is "DES")

    168 (when using -genseckey and -keyalg is "DESede")

-validity 90

In generating a public/private key pair, the signature algorithm (-sigalg option) is derived from the algorithm of the underlying private key: If the underlying private key is of type "DSA", the -sigalg option defaults to "SHA1withDSA", and if the underlying private key is of type "RSA", -sigalg defaults to "MD5withRSA".

-------------------------------------------

Defaults for keytool command in Java 1.7 :

-alias "mykey"

-keyalg

    "DSA" (when using -genkeypair)

    "DES" (when using -genseckey)

-keysize

    2048 (when using -genkeypair and -keyalg is "RSA")

    1024 (when using -genkeypair and -keyalg is "DSA")

    256 (when using -genkeypair and -keyalg is "EC")

    56 (when using -genseckey and -keyalg is "DES")

    168 (when using -genseckey and -keyalg is "DESede")

-validity 90

If the underlying private key is of type "DSA", the -sigalg option defaults to "SHA1withDSA"

If the underlying private key is of type "RSA", the -sigalg option defaults to "SHA256withRSA".

If the underlying private key is of type "EC", the -sigalg option defaults to "SHA256withECDSA".

 -------------------------------------------- 

The chaining can be of 2 types :

root……………………….ow = xxx

……………………………..is= xxx

inter ……………………… ow= xxx

………………………………is= yyy

signedcert……………….. ow= yyy

……………………………… is= ppp

and

signedcert ……………… ow= ppp

…………………………….. is= yyy

inter……………………… ow= yyy

…………………………….. is= xxx

root………………………. ow= xxx

…………………………….. is= xxx

Steps to configure SAML 2.0 with Weblogic Server (using Oracle DB as a RDBMS security store)...

 What is SAML 2.0 ?

Security Assertion Markup Language 2.0 (SAML 2.0) is a version of the SAML standard for exchanging authentication and authorization data between security domains.

SAML 2.0 is an XML-based protocol that uses security tokens containing assertions to pass information about a principal (usually an end user) between a SAML authority, that is an identity provider, and a SAML consumer, that is a service provider

It enables cross-platform authentication between Web applications or Web services running in a WebLogic domain and Web browsers or other HTTP clients.

When users are authenticated at one site that participates in a single sign-on (SSO) configuration, they are automatically authenticated at other sites in the SSO configuration and do not need to log in separately.

One who generated the SAML token is called the Identity Provider OR Asserting Party OR Source Site.

And the one accepts the token is called the Service Provider OR Relying Party OR Destination Site.
Trust has to be established between them for SAML to work hence details of the Service Provider has to be with the Identity Provider and details of Identity Provider has to be with the Service Provider.

SAML can be classified into two types depending on the manner in which requests are obtained.

- IDP initiated ( Identity Provider Initiated )

- SP initiated ( Service Provider initiated )

-------------------------- 

- The RDBMS security store is required by the SAML 2.0 security providers in production environments so that the data they manage can be synchronized across all the WebLogic Server instances that share that data.

- Note that Oracle does not recommend upgrading an existing domain in place to use the RDBMS security store. If you want to use the RDBMS security store, you should configure the RDBMS security store at the time of domain creation. If you have an existing domain with which you want to use the RDBMS security store, create the new domain and migrate your existing security realm to it.

- For testing purpose you can use embedded LDAP instead of an external RDBMS store. 

In this post we will see how to configure SAML2 with Weblogic Server using Oracle DB as a RDBMS security store.
