HOW TO SAML Password Management (Note)

Antonio Musarras Blog The ideal solution for a problem Blog: http://musarra.wordpress.com Mail: antonio.musarra@gmail.com HOW TO SAML Password Management (Note) Hi Freddy, Today I got to spend about 2 hours to the issue of configuring SAML analyzing the source code of SugarCRM. I got some interesting information, so I decided to gather all the information in this document that might help you. 1. Official documentation that describes how to setup SAML is http://www.sugarcrm.com/crm/support/documentation/SugarEnterprise /6.2/-‐docs-‐Application_Guides-‐ Sugar_Enterprise_Application_Guide_6.2.0RC3-‐Administration.html -‐ 1916827 2. I analyzed the classes in modules/Users/authentication/ SAMLAuthenticate The scenario of Single Sign On via SAML that I expect from SugarCRM should be the one shown in Figure 1. Do you confirm that the scenario I described is correct? Analyzing the source code, in particular the file modules/Users/authentication/SAMLAuthenticate/settings.php, I found a number of very useful information which are: 1. The parameter const_assertion_consumer_service_url is the URL where to the SAML Response/SAML Assertion will be posted. The value (for example: http://sugarcrm-‐fe-‐1.local/index.php?module=Users& action=Authenticate) of this parameter should be considered in configuring the Identity Server as the Assertion Consumer URL. 2. The parameter const_issuer is the name of the application that in this case is fixed to php-‐saml. This value should be used as the Issuer on the Identity Server configuration. 3. The parameter SAML_loginurl (or Login URL), must be valorized with the URL of the Identity Server login page. This URL is then added to the parameter SAMLRequest. See the file modules/Users/authentication/SAMLAuthenticate/lib/onelogin/saml/au threquest.php Based on the above information, the configuration of the scenario should be the one shown in Figure 2 and Figure 3. Do you confirm that what I explained is correct? With the appropriate modifications are able to do generate and send AuthnRequest to the Indentity Server (see Figure 4 and Figure 5).
