Old issue with mail and authentication with CAS server

Hello,

I have been using WPCassify since 2017 to authenticate with a CAS server (Cerbere). Problem is the login used is the mail address and we need to create user accounts based on the email.

Initially the module did not work fine so I had to patch it and I have to keep patching it . Here is the latest version (2.3.1) patched, I would like to know if there is a possibility to merge my patch or include hooks in the right places to replace my patches ?

Thanks in advance
