Need to use urn:federation:authentication:windows for requestedAuthnContext

[quentinsup]

Hello,

Thanks for your work !

I need to specify the value 'urn:federation:authentication:windows' for requestedAuthnContext conffiguration, but there is configuration control with do not permit to use something diffrent from 'urn:oasis:names:tc:SAML:2.0:ac:classes:' (Configuration.php, line 169)

Why (It does not appear that php-saml lib is so restricted) ? How can I fix this ?

->variableNode('requestedAuthnContext')
                                        ->validate()
                                            ->ifTrue(static fn ($value) => !(\is_bool($value) || \is_array($value)))
                                            ->thenInvalid('must be an array or a boolean.')
                                        ->end()
                                        ->validate()
                                            ->ifTrue(static fn ($value) => \is_array($value) && array_filter($value, static fn ($item): bool => !str_starts_with($item, 'urn:oasis:names:tc:SAML:2.0:ac:classes:')))
                                            ->thenInvalid('invalid value.')
                                        ->end()
                                    ->end()
