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.

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.

Steps to create a .jks keystore using .key and .crt files...

How to create a .key and .crt file ?

If we already have a .key and .crt file how do we import them into a .jks keystore file ? 

How to convert a certificate from DER format to PEM format ? 

Keytool cannot import/export a private key into a keystore file.

To import a private key we need to use other tools like openssl.

We have seen situations when in we get a .key and .crt file from our vendors and we need to import the same into a .jks keystore to configure SSL with WLS.

Here .crt is the signed certificate from a CA and .key contains the private key.

To import these two files into a .jks keystore we can use the following command :

Syntax : $ java utils.ImportPrivateKey keystore storepass storetype keypass alias certfile keyfile keyfilepass

The ImportPrivateKey utility is used to load a private key into a private keystore file.

You can use the CertGen utility to create a .key ( testkey ) and .crt ( testcert ) and then use the ImportPrivateKey utility to create a .jks file.

Note: By default, the CertGen utility looks for the CertGenCA.der and CertGenCAKey.der files in the current directory, or in the WL_HOME/server/lib directory, as specified in the weblogic.home system property or the CLASSPATH.

Alternatively, you can specify CA files on the command line. If you want to use the default settings, there is no need to specify CA files on the command line.

1. Enter the following command to generate certificate files named testcert with private key files named testkey:

Command : $ java utils.CertGen -keyfilepass mykeypass -certfile testcert -keyfile testkey

2. Convert the certificate from DER format to PEM format.

Command :  $ java utils.der2pem CertGenCA.der

3. Concatenate the certificate and the Certificate Authority (CA).

Command :  $ cat testcert.pem CertGenCA.pem >> newcerts.pem

4. Create a new keystore named mykeystore and load the private key located in the testkey.pem file.

Command :  $ java utils.ImportPrivateKey -keystore mykeystore -storepass mypasswd -keyfile mykey -keyfilepass mykeypass -certfile newcerts.pem -keyfile testkey.pem -alias passalias

In this post we will see how to import a .crt and .key file into a .jks file.

Steps to create a self-signed certificate and configure Custom Identity and Custom Trust with Weblogic Server using Keytool...

 What are self signed certificates and how to create them ?

A self-signed certificate is an identity certificate that is signed by the same entity whose identity it certifies.

 This term has nothing to do with the identity of the person or organization that actually performed the signing procedure. In technical terms a self-signed certificate is one signed with its own private key.
 Note :
 Identity keystores must contain a private key entry
 Trust store must contain all trusted key entries
 Below are few default values when using keytool command on JDK 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

Note :

-genkey is used in the example here. This was an old name used in previous releases. This old name is still supported in this release and will be supported in future releases, but for clarify the new name, -genkeypair, is preferred going forward.

Changes in keytool in Java 1.6 :

keytool no longer displays password input when entered by users. Since password input can no longer be viewed when entered, users will be prompted to re-enter passwords any time a password is being set or changed (for example, when setting the initial keystore password, or when changing a key password).

Some commands have simply been renamed, and other commands deemed obsolete are no longer listed in this document. All previous commands (both renamed and obsolete) are still supported in this release and will continue to be supported in future releases. The following summarizes all of the changes made to the keytool command interface:

Renamed commands:

-export, renamed to -exportcert
-genkey, renamed to -genkeypair
-import, renamed to -importcert
Commands deemed obsolete and no longer documented:

-keyclone
-identitydb

-selfcert

In this post we will see how to create self-signed cretificates and configure it Weblogic Server 10.3.6 ( CustomIdentityandCustomTrust ).

Steps to configure SAML 2.0 with Weblogic Server (using embedded LDAP as a security store - Only for Dev Environment)...

 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 )

In this post we will see how to configure Single sign-on (SSO) using SAML 2.0 in Weblogic Server.
