SCIM is a standard for cloud-based identity management for single sign-on (SSO) in browsers. It is a RESTful protocol for identity account management operations.%BR% This article will focus on the configuration steps to setup CLM / ELM with JAS for SCIM. ---++ Important Notes and Pre-requisites * It is recommended to upgrade to CLM and JAS Version 6.0.6.1 (with the latest iFix) or higher to configure SCIM with JAS * To configure SCIM you must use Lightweight Directory Access Protocol (LDAP) for User registries in JAS * The screenshots on the SCIM configurations in CLM / ELM are from version 6.0.6.1. In earlier versions there are additional options in SCIM configuration ---++ Installation *CLM* %BR% * To deploy JAS to an existing environment and migrate to JAS, visit this [[https://www.ibm.com/support/knowledgecenter/SSYMRC_6.0.6.1/com.ibm.jazz.install.doc/topics/t_JsaSso_CLM_apps_enable.html][Section]] on our Infocenter * For a new deployment of CLM, Install the applications via IBM Installation Manager and Select the option "Enable Jazz Security Architecture SSO" during the installation%BR%%BR% <img src="%ATTACHURLPATH%/Enable_JAS_SSO.jpg" alt="Enable_JAS_SSO.jpg" width="650" height="250" /> %BR% *JAS* %BR% * Download Jazz Authorization Server install bit from [[https://jazz.net/downloads/clm/releases/6.0.6.1?p=allDownloads][jazz.net]], under All Downloads Section for the specific version%BR%%BR% <img src="%ATTACHURLPATH%/JAS_Download.jpg" alt="JAS_Download.jpg" width="400" height="75" /> %BR%%BR% * Install Jazz Authorization Server application via Installation Manager, instructions available on our [[https://www.ibm.com/support/knowledgecenter/SSYMRC_6.0.6.1/com.ibm.jazz.install.doc/topics/t_s_server_installation_im.html][Infocenter]]%BR%%BR% <img src="%ATTACHURLPATH%/JAS_Install.jpg" alt="JAS_Install.jpg" width="600" height="200" /> %BR% ---++ Setup and Configure JAS for SCIM with LDAP Registry ---+++ Configuration files * Copy the files from =[JazzAuthServer_Install_Dir]/wlp/usr/servers/jazzop/defaults= folder one level up to =[JazzAuthServer_Install_Dir]/wlp/usr/servers/jazzop/= * Files we would modify are =server.xml=, =appConfig.xml= and =ldapUserRegistry.xml= * =appConfig.xml= -

It is not recommended to use Derby database for a production environment and note that Derby database won't work in a clustered JAS environment, since that information won't be available to all the instances. The basic steps to configure the database are: * Create database tables on a database server which all JAS instances can access * Update the JAS configuration file (appConfig.xml) to use the database server The following links provide information for Oracle, MSSQL and DB2 database servers and sample SQL scripts are available that can create the necessary tables. But note that you will need to customize these scripts for your own environment. * [[https://jazz.net/wiki/bin/view/Deployment/PerformanceClusteredJAS#DB2][Configure IBM DB2 Database]] * [[https://jazz.net/wiki/bin/view/Deployment/PerformanceClusteredJAS#Oracle][Configure Oracle Database]] * [[https://jazz.net/wiki/bin/view/Deployment/PerformanceClusteredJAS#Microsoft_SQL_Server][Configure Microsoft SQL Server Database]] ---+++ Test SCIM * Now that JAS is configured with LDAP and SCIM, it is time to start and test if it is configured right * Start the server (*Linux example*) <verbatim> $ cd JazzAuthServer_install_dir $ ./start-jazz </verbatim> * Access the following URLs to test JAS and SCIM configuration * JAS Configuration URL (Default value for a new setup is _data [ ]_ ) %BR% https://fully_qualified_domain_name_of_JAS_server:defined_port/oidc/endpoint/jazzop/.well-known/openid-configuration %BR% https://fully_qualified_domain_name_of_JAS_server:defined_port/oidc/endpoint/jazzop/registration * Confirm the SCIM API for Users with this URL %BR% https://fully_qualified_domain_name_of_JAS_server:defined_port/ibm/api/scim/Users * Confirm the SCIM API for Groups with this URL %BR% https://fully_qualified_domain_name_of_JAS_server:defined_port/ibm/api/scim/Groups %BR% ---++ Jazz Team Server (JTS) Setup with JAS and SCIM * For a new deployment, CLM installation should be enabled for Jazz Security Architecture SSO * Ensure pop-up blocker is disabled on the browser, or Pop-ups are allowed for CLM and JAS URLs * Accessing the JTS setup page https://jtsserver:port/jts/setup , would not prompt for a Username / Password * Express setup would be disabled for a CLM instance enabled for Jazz Security Architecture SSO %BR% <img src="%ATTACHURLPATH%/JTS_Setup.png" alt="JTS_Setup.png" width="600" height="125" /> %BR% * Run through JTS setup following the prompts until you reach "Register Applications" Page * Enter the Jazz Authorization Server details. *The URL you enter should be accessible by all and is as important as the Jazz Public URI* %BR% %BR% <img src="%ATTACHURLPATH%/JAS_Server.png" alt="JAS_Server.png" width="575" height="350" /> %BR% * In the Next step (Step 6), "Select a type of User Registry", select SCIM %BR% %BR% <img src="%ATTACHURLPATH%/SCIM_Config.png" alt="SCIM_Config.png" width="550" height="375" /> %BR% %BR% * Enter the SCIM Provider URL and Bind User Information %BR% <img src="%ATTACHURLPATH%/SCIM_Registry_6061.png" alt="SCIM_Registry_6061.png" width="650" height="600" /> %BR% %BR% =Note: The _Jazz Group to Registry Group Mapping_ configuration is important for User to jazz group role mapping.
