Two issues with associate user account

[jasom]

etesync-dav 0.32.1 NixOS

Account typically uses iOS, but I have also replicated the issues with cadaver.

1. Every other login fails on the client with a 500 error; radicale logs show a successful login
2. Once logged in, PROPFIND requests on any collection usually (but not always) return an error. service logs from that error included below.

I have not been able to reproduce either of these problems on the main account, just the associate account.
