I upgraded moodle to the latest which is Moodle 4.1.1+ (Build: 20230120). Prior to that I was running PhP.7.3, so I upgraded to PhP 7.4.33 since this version of moodle required it.
My users were being synced with an external database using mssqlnative and everything was working fine. After this upgrade any user trying to login is presented with "mssqlnative extension not installed"
I have done various searches and nothing is of help. This is on an Ubuntu server 18.04. Any insights would be greatly appreciated. Note, this was working on the previous version of moodle and php.
