function cas_invoke_auth_transform in CAS 5

Same name and namespace in other branches

1. 5.4 cas.module \cas_invoke_auth_transform()
2. 5.3 cas.module \cas_invoke_auth_transform()
3. 6.2 cas.module \cas_invoke_auth_transform()

Invokes hook_auth_transform() in every module.

Other modules may need to transform the results of phpCAS::getUser() into a Drupal username (i.e. phpCAS::getUser() is not guaranteed to return the same username that the user typed in or the Drupal username might be username@cas or something and we need to know it before we filter)

We cannot use hook_insert or any user hooks, because they fire way too late. We cannot use module_invoke_all(), because the argument needs to be passed by reference.

Parameters

$cas_user: The cas reply string to transform into a drupal username

1 call to cas_invoke_auth_transform()

cas_login_check in ./cas.module

Implementation of hook_init Traps a page load to see if authentication is required.

File

./cas.module, line 28
