Environment


  • Prisma Cloud
  • Identity Provider (IdP) supporting SAML SSO

Cause


  • There are mainly two URLs that need to be configured correctly on the IdP side.

Audience URI (SP Entity ID)
 
  • Can be copied from Prisma Cloud SSO page and is unique for your tenant. 
  • This is a read-only field in the format: https://app.prismacloud.io?customer=<string> to uniquely identify your instance of Prisma Cloud.
  • You require this value when you configure SAML on your IdP.

Reply URL (Assertion Consumer Service URL)
 
  • Depending on the location of your tenant, which is displayed in the login URL, replace ‘api’ with ‘api2’ or ‘api.eu’.
  • For example: https://api2.prismacloud.io/saml.

Error message "Unexpected value of required field SAML_DESTINATION_URI" is faced when the 'Reply URL' on the IdP side is misconfigured.

Resolution


  • Change the 'Reply URL' on the IdP side. 
For Example, if your tenant is hosted on app.ind, change the Reply URL to https://api.ind.prismacloud.io/saml
