Configure SAML single sign-on
To provide single sign-on capabilities across applications that are hosted on the service provider, you can configure SAML single sign-on on the SAML SP.
Configuring SAML single sign-on by using the command line interface
-
Configure the SAML SSO profile.
Example
In the following command, Example is the load balancing virtual server that has a web link from the SharePoint portal. Nssp.example.com is the Traffic Management virtual server that is load balancing the SharePoint server.
add tm samlSSOProfile tm-saml-sso -samlSigningCertName nssp -assertionConsumerServiceURL "https://nssp2.example.com/cgi/samlauth" -relaystateRule "\\"https://nssp2.example.com/samlsso.html\\"" -sendPassword ON -samlIssuerName nssp.example.com -
Associate the SAML SSO profile with the traffic action.
Example
The following command enables SSO and binds the SAML SSO profile created above to a traffic action.
add tm trafficAction html_act -SSO ON -samlSSOProfile tm-saml-sso -
Configure the traffic policy that specifies when the action must be run.
Example
The following command associates the traffic action with a traffic policy.
add tm trafficPolicy html_pol "HTTP.REQ.URL.CONTAINS(\\"abc.html\\")" html_act -
Bind the traffic policy created previously to a traffic management virtual server (load balancing or content switching). Alternatively, the traffic policy can be associated globally.
Note
This traffic management virtual server must be associated with the relevant authentication virtual server that is associated with the SAML action.
bind lb vserver lb1_ssl -policyName html_pol -priority 100 -gotoPriorityExpression END -type REQUEST
Configuring SAML single sign-on by using the GUI
To configure SAML single sign-on you need to define the SAML SSO profile, the traffic profile, and the traffic policy and bind the traffic policy to a traffic management virtual server or globally to the NetScaler appliance.
