Additional information
Snippet from the error log:

PHP Fatal error: Uncaught PDOException: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'username' at row 1 in /var/www/html/ojs-3.3.0-13/lib/pkp/lib/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOStatement.php:115\nStack trace:\n#0 /var/www/html/ojs-3.3.0-13/lib/pkp/lib/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOStatement.php(115): PDOStatement->execute()\n#1 /var/www/html/ojs-3.3.0-13/lib/pkp/lib/vendor/laravel/framework/src/Illuminate/Database/Connection.php(489): Doctrine\\DBAL\\Driver\\PDOStatement->execute()\n#2

Steps I took to investigate the issue
After digging through the code I suspect the problem lies within the ShibbolethHandler.inc.php, line 555:
$user->setUsername($userEmail);

It seems like the userEmail is simply assigned here to the username without any further formatting. However, the character_maximum_length of the username is 32 and furthermore only alphanumeric characters are allowed.

Any help is appreciated!

Best,

Edit:
I was able to confirm that the problem is said assignment $user->setUsername($userEmail);.
Setting the user to a string that fits the username criteria ($user->setUsername("testuser123");) resulted in successful registration.
