Update PHP to 8.3 and above breaks LDAP

Weirdly enough, my projeqtor on this instance is on 12.3.3, as I never go to the current one (12.4.1), I'm always using the previous stable version
I'll update PHP to 8.3 and 8.4 again and record the log as I forgot to do it before reverting to a backup

Thank you

Hello again, (sorry for the wait)

Here are the information about our testing instance (the one we update first to see if everything work)
Debian 13.3
PHP 8.2.29
Projeqtor 12.4.4

The problems I encounter are as follow
after updating to PHP 8.4 (8.4 now since it got a new version since) and adding all the extentions back (and reconfiguring the php.ini)
I can't log in and get this error in the log
 
I had forgotten to re-add the LDAP extention for PHP (2 first lines)

and then it tells me I have this problem of ldap°connect with two arguments
This is the ldap config in Projeqtor
 

Also, There doesn't seem to be any mail being sent anywhere on any of my Projeqtor instance since a few month
even using the test send in the global settings in Projeqtor to myself (and 0 error recorded, its green and all)
Openssl is installed properly and it worked before
