[bug] Large user directories result in unusable list

[makinbacon21]

While the dropdown User selection is great for PCs with a few users, adding more than ~30 users or a super large Active Directory service makes this unusable. IMO, there should be a manual username entry field if you have more than like 5 users, but the minimum viable solution here would just be making the list scrollable and fixing the duplicated entries for LDAP systems.

I have sort of the opposite problem. My AD users are not shown in the user list (only local accounts). I joined the system to the domain with:

sudo realm join -U Administrator ad1.example.com
sudo pam-auth-update --enable mkhomedir
sudo realm permit --all

I didn't try any tweaking yet but I can login with an AD account on the console. I'm using a fresh install of the latest Pop-OS Alpha. Can you share any other steps you had to perform to get the AD users to show up in the greeter?
