Mathew Alden's questions

I have a work computer currently running Windows 11 Home. (I will update it to Pro/Enterprise, but I need to get this figured out first.) I need to "set up a work or school account" by connecting to my company's Azure Active Directory. All of the tutorials say that I should just click "join this device to Azure Active Directory", but my computer simply doesn't give me this option. I've been googling this for a few hours, but I haven't been able to figure out why this option is missing. What steps must I take in order to connect my computer to Azure Active Directory?

I'm trying to configure the mod_auth_sspi module on my Apache server. I've found a few example configurations, but I can't find any proper documentation. Does anyone know where I can find that?

My company has an Apache server running PHP 5.4. My task is to update it to PHP 7.4.

The old php.ini file includes a mysqli.cache_size property. I can't find any documentation on this property. Does it still exist in PHP 7? Could anyone link me to the documentation?

Thanks!
