SAP WebGUI Single Sign-On SSO

---

Single Sign-On (SSO) solution by miniOrange provides secure Single Sign-On access into SAP WebGUI using a single set of login credentials. You can log into SAP WebGUI using miniOrange credentials or Azure AD credentials or any of your existing identity providers. With miniOrange SSO services, along with SAP WebGUI you can also login into other On-Premise and Cloud Applications using your existing Identity Providers/User Store (Azure Active Directory, Okta, Ping) credentials . Follow the given setup guide to integrate header-based SSO for your SAP WebGUI account.

Prerequisites for setting up the miniOrange SSO Connector

• Create an account on miniOrange Cloud or set up the miniOrange Identity Server using this document.
• Download the miniOrange SSO Connector [Contact Us to request for the archive].

Follow the Step-by-Step Guide given below to Configure and tests SAP WebGUI Platform

1. Configure SAP WebGUI in miniOrange

• Login into miniOrange Admin Console.
• Go to Apps and click on Add Applicaton button.



• In Choose Application Type click on Create App button in OAUTH/OIDC application type.



• Search for SAP WebGUI in the list, if you don't find SAP WebGUI in the list then, search for OAuth2/OpenID Connect and you can set up your application via OAuth2/OpenID Connect App.



• Enter the Client Name of your app.
• Copy the Redirect-URL from miniOrange SSO connector.
• Adjust time validity for the tokens.
• Then, click on Save.



• To get the Client id,Client secret, OAuth endpoints and scope, you need to edit the application which you have created in the previous steps.

You can edit Application by using the following steps:

• Go to Apps.
• Search for your app and Click on the edit in Action menu against your app.



• Click on Click here to get the miniOrange endpoints.



• Note down all the parameters (Client id,Client secret,OAuth endpoints and scopes). You will need this info while configuring SAP WebGUI with miniOrange.

OAuth endpoints:

Authorization Endpoint:	https://login.xecurify.com/moas/idp/openidsso (Note: Use this endpoint only if you want to use miniorange as oauth identity server.) https://login.xecurify.com/moas/broker/login/oauth/260174 (Note: Use this enpoint only if you are configuring any Identity Provider in Identity Providers Menu and not using miniorange as IDP.)
Token Endpoint:	https://login.xecurify.com/moas/rest/oauth/token
User Info Endpoint:	https://login.xecurify.com/moas/rest/oauth/getuserinfo
Introspection Endpoint:	https://login.xecurify.com/moas/rest/oauth/introspect
Revoke Endpoint:	https://login.xecurify.com/moas/rest/oauth/revoke
OpenID Single Logout Endpoint:	https://login.xecurify.com/moas/idp/oidc/logout?post_logout_redirect_uri=




OAuth Scopes:

email:	View email address of the user
profile:	View profile attributes of the user account
openid:	Retrieve JWT token for OpenID Connect

2. Configure SSO in SAP WebGUI

• Install a Web Server such as Apache Web Server so that SAP Applications are proxied through a Web Server
• Configure the proxy rules in the Web Server to forward the traffic to backend SAP Web Servers for SAP context /irj.
$ cat sap_proxy.conf ProxyPreserveHost On ProxyRequests Off ProxyPass /irj http://sap.example.com:8080/irj ProxyPassReverse /irj http://sap.example.com:8080/irj $

• Install miniOrange – SSO Client in the Web Server to protect the web resources.
• Protect the SAP URI /irj
• Stop the SAP J2EE Dispatcher and server services
• Backup SAP_Engine_Install_Dir\ume\authschemes.xml.bkp to authschemes.xml and open in a text editor to add SSO Scheme to read SSO User Token – HTTP Headers. OB_USER is the default header name for SSO header in SAP, however we recommend using MO_USER.
<authscheme-refs> <authscheme-ref name="default"> <authscheme>SSO <authscheme>uidpwdlogon </authscheme-ref> </authscheme-refs> .. .. <authscheme name="SSO"> <loginmodule> <loginModuleName> com.sap.security.core.logon.imp.HeaderVariableLoginModule </loginModuleName> <controlFlag>REQUISITE <options>Header=MO_USER </loginmodule> <priority>5 <frontEndType>2 <frontEndTarget>com.sap.portal.runtime.logon.header </authscheme>

• Enable SSO Logoff URL
  >>Administration interface >> System Administration >> System Configuration
  >> Configuration >> Direct Editing and add the logoff URLs:
ume.logoff.redirect.url=http(s)://acme.ssogen.com/ssogen/ssologout ume.logoff.redirect.silent=false

• Update HeaderVariableLoginModule with the following variable

Module Name, Flag, Options

EvaluateTicketLoginModule, SUFFICIENT, ume.configuration.active=true
HeaderVariableLoginModule, OPTIONAL, ume.configuration.active=true,Header=MO_USER
CreateTicketLoginModule, SUFFICIENT, ume.configuration.active=true
BasicPasswordLoginModule, REQUISITE,
CreateTicketLoginModule, OPTIONAL, {ume.configuration.active=true}

• Add HeaderVariableLoginModule for each application to support SSO
  Launch Visual Administrator tool >> Choose Policy Configurations >> Authentication
  Add HeaderVariableLoginModule for each application to support SSO.
• Restart the whole SAP System and SAP Applications.

5. Adaptive Authentication with SAP WebGUI

A. Restricting access to SAP WebGUI with IP Blocking

You can use adaptive authentication with SAP WebGUI Single Sign-On (SSO) to improve the security and functionality of Single Sign-On. You can allow a IP Address in certain range for SSO or you can deny it based your requirements and you can also challenge the user to verify his authenticity. Adaptive authentication manages the user authentication bases on different factors such as Device ID, Location, Time of Access, IP Address and many more.

You can configure Adaptive Authentication with IP Blocking in following way:

• Login to Self Service Console >> Adaptive Authentication.
• Add a Policy Name for your Adaptive Authentication Policy.



• Select your Action for behaviour Change and Challenge Type for user from the Action for behaviour Change Section.





Action for behaviour Change Options :




Attribute	Description
Allow	Allow user to authenticate and use services if Adaptive authentication condition is true.
Challenge	Challenge users with one of the three methods mentioned below for verifying user authenticity.
Deny	Deny user authentications and access to services if Adaptive authentication condition is true.




Challenge Type Options :




Attribute	Description
User second Factor	The User needs to authenticate using the second factor he has opted or assigned for such as OTP over SMS PUSH Notification OTP over Email And 12 more methods.
KBA (Knowledge-based authentication)	The System will ask user for 2 of 3 questions he has configured in his Self Service Console. Only after right answer to both questions user is allowed to proceed further.
OTP over Alternate Email	User will receive a OTP on the alternate email he has configured threw Self Service Console. Once user provides the correct OTP he is allowed to proceed further.



• Now Enable Enable IP Restriction option from the IP RESTRICTION CONFIGURATION section to configure custom IP range.



• Select the Action you want to perform if the IP address is out of the range. i.e. Allow, Challenge & Deny.
• Specify the IP Address range for which you want above setting to reflect. You can add more than one IP Address ranges by clicking on following button +.

B. Adaptive Authentication with Limiting number of devices.

Using Adaptive Authentication you can also restrict the number of devices the end user can access the Services on. You can allow end users to access services on a fixed no. of devices. The end users will be able to access services provided by us on this fixed no. of devices.

You can configure Adaptive Authentication with Device Restriction in following way


• Login to Self Service Console >> Adaptive Authentication.
• Add a Policy Name for your Adaptive Authentication Policy.
• Select your Action for behaviour Change and Challenge Type for user from the Action for behaviour Change Section.




• Scroll down to Device Configuration section and enable Allow User to Register Device option to allow users to register their devices.
• Enter the Number of Devices which are allowed to register in field next to Number of Device Registrations Allowed
• Choose Action if number of devices exceeded (This will override your setting for Action for Behaviour Change.)
1. Challenge: The user needs to verify himself using any of the three methods mentioned in table in step 5.1
2. Deny : Deny users access to the system
• Enable option Send email alerts to Users if number of Device registrations exceeded allowed count if you want to alert the user about no of devices exceeding the limit. Save the configuration.
