LDAP error in Nextcloud 13 beta1


I just upgraded to Nextcloud 13 beta1 (user_ldap version: 1.3.1) and this error appears over and over in the logs when an LDAP user does any action, even when clicking a button or reloading the page.

bin2hex() expects parameter 1 to be string, array given at /var/www/nextcloud/apps/user_ldap/lib/Access.php#1638

Everything seems to work fine for now, but even if this is a harmless error it fills the logs pretty quick with just one LDAP user logged in. With a few dozens of active users it will produce way more logs than wanted. Anyone know where this error comes from and how could it be fixed?

Please report this directly to the bug tracker: https://github.com/nextcloud/server/issues

ok, thanks
