Hi,

as far as I can see, the metadata generation is only there to help you get 
started. Once it’s there it should never need to be auto-generated again. I 
just edit the files by hand. In the end, this document does not influence CAS’s 
behaviour but informs your SPs about endpoints, capabilities etc. The 
behaviour, e.g. issuer in SAML responses, is controlled by the properties 
files, so there has to be a matching between properties and metadata for your 
SPs to trust it.

Also make sure your certificates contain the right hostname and so on.

Cheers Arnold

Betreff: [cas-user] SAML 2 unable to change idpEndPoint

Hi all, first time posting, hopefully I am not asking a stupid question.

Scope:
I am using CAS 5.1.1 with SAML 2 protocol, my server act as an idp.

Problem:
When I tried to generate an idp-metadata.xml by modifying some CAS properties, 
no matter how I change it I can't modified out the cas.example.org

I found my research that cas.example.org links to an variable called 
${idpEndPoint}, and it seems to link to cas.host.name, but changing 
cas.host.name and other host info doesn't seems to modified  ${idpEndPoint}, am 
I doing something wrong?

I also tried removing idp-metadata.xml completely and try generate a new one, 
didn't works too.

Any helps would be appreciated :D

Code:
idp-metadata.xml
