Questions on pac4j saml module

[Julien Gribonvald]

Hi folks,

I have few questions about the pac4j saml configuration:

• is there a way to customize the button generated with the clientName text on CAS login page ? I mean using a displayName and a description, is there something already existing or I could purpose a Pull Request to be able to customize ?
• How are you generating metadata after cas server launch ? the default configuration generate metadatas if they doesn't exist only when a request is made, I would like that these metadatas available when the cas is available, like that IDPs can request them before a user access !
  
• what is the best way to share files generated (metadata, keystore, certificates) between each CAS instance used in load-balancing (not in cluster) ? I'm using a git repo to share my configurations only (in the /xxx/cas-properties/), but I'm not sure that is a good practice, even more if we delete certificates and metadata to renew them. What are your advices/practices ?

Thanks
