Setting Up SAML 2.0 Single Sign-On (SSO)
Software Requirements
Ensure your D3 SOAR version is 14.0.385 or higher.
Prerequisites
For the SAML service, you'll need:
Assertion Consumer Service URL (Reply URL): This is the SP's (Service Provider) endpoint URL where the IdP (Identity Provider) will send the SAML response after successful authentication. Typically, this is specific to your D3 VSOC/Admin login URL. For example,
https://***.com/VSOC/login.aspx
.Entity ID: This unique identifier helps the IdP identify the SP. Generally, this is set to the Assertion Consumer Service URL.
For the D3 application, you'll need:
SAML Single Sign-On URL: This is the IdP's URL where the authentication requests and SAML responses are exchanged.
SAML Certificate: A SAML certificate in base64 format.
Configuring the D3 Application
When you complete the following configuration, here's how the system will behave:
Users trying to access the D3 application via the URL https://***.com/VSOC will be directed to the SAML single sign-on page. Direct access to the D3 application through https://***.com/VSOC/login.aspx is not permitted.
After the user is authenticated by the IdP and the SAML response is verified by the D3 application, they will gain access to the D3 application.
Users are restricted from directly accessing the D3 Admin application and should instead navigate through the Advanced Settings within the VSOC application.
If a user remains idle in the D3 application, they will be prompted after 115 minutes. If they fail to respond within 5 minutes, they will be automatically signed out and redirected to the D3 sign-out page. They can return to the application by clicking the "Return to Sign in" button.
To enable complete sign-out for the client, set the
LogoutSamlWithVSOC
key totrue
in theappSettings
for both VSOC and Admin applications. Also, set theSAMLLogOutUrl
to the client's SAML sign-out URL. Following these settings, users will be redirected to the specified URL instead of the D3 sign-out page after being signed out.
Steps to Configure
Step 1 - Configure VSOC App Settings
Open Web.Config
for the VSOC app and modify the authentication options and appSettings
as shown.
Modify authentication options:
<authentication mode="Forms">
<forms loginUrl="D3Saml.aspx?reset=true" name="AuthCookie" timeout="140"
path="/" requireSSL="false">
</forms>
</authentication>
<add key="InactivityExpiry" value="120" />
<add key="TimeBeforeWarning" value="5" />
<add key="enableSAMLLogin" value="true" />
<add key="SAMLLogin" value="Login.aspx" />
<add key="SAMLExchangBaseUrl" value="" />
<add key="SAMLExchangeTargetUrl" value="login.aspx" />
<add key="SAMLLogOutUrl"
value="https://login.microsoftonline.com/common/wsfederation?wa=wsignout1.0" />
<add key="logoutSamlWithVSOC" value="false" />
<add key="SAML2.0" value="true" />
<add key="SAML2.0LogFolder" value="Log\SAML" />
<add key="SAML2.0Conigfile" value="SAML20\SAML.xml" />
Then, modify the
appSettings
to confirm thesessionState
options.
<sessionState mode="InProc" cookieless="false" timeout="300" />
Reader Note
Set the value of
forms.timeout
toappSettings.InactivityExpiry
+ 20.Ensure that the value of
appSettings.SAMLExchangBaseUrl
is set to an empty string.Only set
appSettings.logoutSamlWithVSOC
to true if the client has provided a value forappSettings.SAMLLogOutUrl
.
Step 2 - Configure Admin App Settings
Open Web.Config
for the Admin app and modify the authentication options and appSettings
as shown.
Modify the authentication options:
<authentication mode="Forms">
<forms name="MYWEBAPP.ASPXAUTH" loginUrl="login.aspx?RE=true"
timeout="140" path="/" requireSSL="false">
</forms>
</authentication>
Modify
appSettings
:
<add key="Session.TimeOut" value="130" />
<add key="enableSAMLLogin" value="true" />
<add key="SAMLLogin" value="Login.aspx" />
<add key="SAMLExchangBaseUrl" value="" />
<add key="SAMLExchangeTargetUrl" value="login.aspx" />
<add key="SAMLLogOutUrl"
value="https://login.microsoftonline.com/common/wsfederation?wa=wsignout1.0" />
<add key="logoutSamlWithVSOC" value="false" />
<add key="SAML2.0" value="true" />
<add key="SAML2.0LogFolder" value="Log\SAML" />
<add key="SAML2.0Conigfile" value="SAML20\SAML.xml" />
Then, confirm the
sessionState
options.
<sessionState mode="InProc" cookieless="false" timeout="300" />
Reader Note
Set the value of
appSettings.Session.Timeout
toVSOC.appSettings.InactivityExpiry
+ 10Ensure that the value of
appSettings.SAMLExchangBaseUrl
is set to an empty string.Set the value of
forms.timout
toVSOC.appSettings.InactivityExpiry
+ 20.
Step 3 - Configure Application Pool
Verify the application pool settings and ensure VSOC and Admin applications use the same application pool.
Confirm the application pool settings:
(General)
Enable 32-Bit Applications: False
Process Model:
Idle Time-out (minutes): 140
Recycling:
Generate Recycle Event Log Entry:
Application Pool Configuration Changes: True
Isapi Reported Unhealthy: True
Manual Recycle: True
Private Memory Limit Exceeded: True
Regular Time Interval: True
Request Limit Exceeded: True
Specific Time: True
Virtual Memory Limit Exceeded: True
Regular Time Interval (minutes): 0
Specific Times: (None)
Configure VSOC and Admin applications to use the same application pool.
Reader Note
Set the value of Idle Time-out to VSOC.appSettings.InactivityExpiry
+ 20
Step 4 - Configure SAML 2.0
You will need to adjust the configuration file, located at: <VSOC or Admin app path>\SAML20\SAML.xml
.
| The Assertion Consumer Service URL provided by the Service Provider (SP) where the Identity Provider (IdP) sends the SAML assertions after successful authentication. Must be set to D3 VSOC/Admin login URL. |
| SAML single sign-on URL. The IdP URL where the authentication requests and SAML responses are exchanged. |
| SAML certificate in base64 format. |
| If the user name used to authenticate with the IdP is in email format but the user name in D3 is not in email format, set the value for EmailIDType to true. |
| Set to true if the SAML response is compressed by the IdP. |
Below is a sample SAML.xml
for reference:
