Hello!

Could someone explain the use of value (evaluationOrder) in services.

The documentation explains:

*evaluationOrder -->* 



*Required value that determines relative order of evaluation of
registered services. This flag is particularly important in cases where
two service URL expressions cover the same services; evaluation order 
determines which registration is evaluated first.*
I understand that if I have 2 defined services:

Service 1

service1-10000001.json
{ 
"@class" : "org.jasig.cas.services.RegexRegisteredService", 
 "serviceId" : "^https://mydomain.org/servicio1.*";, 
 "name" : "HTTPS and HTTP Test", 
 "id" : 10000001, 
 "description" : "Test service which releases all attributes.", 
 "proxyPolicy" : { 
 "@class" : "org.jasig.cas.services.RefuseRegisteredServiceProxyPolicy" 
 }, 

 "evaluationOrder" : 1, 
 "usernameAttributeProvider" : { 
 "@class" : 
"org.apereo.cas.services.PrincipalAttributeRegisteredServiceUsernameProvider",
 "usernameAttribute" : "*PrincipalA*",
 }, 
 "logoutType" : "BACK_CHANNEL", 
 "attributeReleasePolicy" : { 
 "@class" : "org.jasig.cas.services.ReturnAllAttributeReleasePolicy" 
 }, 
 "accessStrategy" : { 
 "@class" : "org.jasig.cas.services.DefaultRegisteredServiceAccessStrategy", 
 "enabled" : true, 
 "ssoEnabled" : true 
 }
}

Service 2

service2-10000002.json
{ 
"@class" : "org.jasig.cas.services.RegexRegisteredService", 
 "serviceId" : "^https://mydomain.org/servicio1.*";, 
 "name" : "HTTPS and HTTP Test", 
 "id" : 10000002, 
 "description" : "Test service which releases all attributes.", 
 "proxyPolicy" : { 
 "@class" : "org.jasig.cas.services.RefuseRegisteredServiceProxyPolicy" 
 }, 

 "evaluationOrder" : 2, 
 "usernameAttributeProvider" : { 
 "@class" : 
"org.apereo.cas.services.PrincipalAttributeRegisteredServiceUsernameProvider",
 "usernameAttribute" : "*PrincipalB*",
 }, 
 "logoutType" : "BACK_CHANNEL", 
 "attributeReleasePolicy" : { 
 "@class" : "org.jasig.cas.services.ReturnAllAttributeReleasePolicy" 
 }, 
 "accessStrategy" : { 
 "@class" : "org.jasig.cas.services.DefaultRegisteredServiceAccessStrategy", 
 "enabled" : true, 
 "ssoEnabled" : true 
 }
}




*When the user accesses the service, if it authenticates with ldapX (service 
evaluationOrder 1) it returns PrinciaplA.
But if it authenticates with ldapXX (service2 evaluationOrder 2) it returns 
PrincipalB.*Thank's.
