Portal menu : display condition with sp: does not work for SAML SP
When using a specific rule to display an application in Menu using sp: , it does work, application is always displayed.
This is because the code in Lib/SAML.pm stores the rule with the entityID key instead of the configuration key. The code in Issuer/SAML.pm also use the entityID key to apply the rule. We should change both to use the SP config key.
