I am using
https://www.mediawiki.org/wiki/Extension:PluggableAuth
and
https://www.mediawiki.org/wiki/Extension:SimpleSAMLphp
On authenticate error, i get directed to simplesamlPhp default error page with an Unauthorized Access message.
I would like to define a custom error message, it seems possible as Pluggableauth authenticate function implemented by SimpleSAMLphp plugin has an errorMessage parameter but i don’t know how to set it.
Any ideas on to do this ?
