Post-processing the attached groups of a user

This hook lets you post-process the typo3_groups that will be attached to a user.

In your extension (in the ext_localconf.php file), register the hook using a code like:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['ig_ldap_sso_auth']['getGroupsProcessing'][]
	= \VendorName\Extension\YourClass::class;

Your class has to implement the \Causal\IgLdapSsoAuth\Utility\GetGroupsProcessorInterface interface. This implies implementing a method called getUserGroups which will receive the following arguments:

$groupTable

The name of the db table for the groups (be_groups vs. fe_groups).

$ldapUser

The full data from ldap of the currently processed user.

$ldapGroups

The array of the groups that have been calculated for this user. passed as reference so you can add/remove items from the list.

This hook is deprecated since version 4.1. You should migrate your code by listening to the PSR-14 events AfterComputeUserGroupsEvent instead.
