Catalina won't let me connect to AFP-Fileserver

[Till_Muc]

Trying to connect with AFP from Catalina (19A536g) to a server running Mojave is not possible. Any ideas?

I am using Cmd K to open the connection, entering afp://[server-ip] – than insert name and PW – this results in spinning wheel forever.

- Login and PW both double checked - they work on Mojave:Mojave connection
- I tried deleting network preferences in System Configuration than reboot. No success
- connecting via browser to that server is possible
- connecting with VNC is possible
- connecting with SMB is not supported by server

I am clueless and appreciate any hint or help

It must be an issue with the Mojave server, it sounds like. My Catalina connects just fine to all AFP servers and they aren’t even Apple devices.

Thanks – if so, it must be an issue Catalina <=> Mojave since all Mojave <=> Mojave connections work fine.

i played a little with the user's settings on the server.
- New user, new password: No success - no login possible (Catalina to Mojave).
- Old user, new login (mail address), new password - no success either.
- Old user, assign new password and ask the user to change his password - that worked. But only once. No more after the next reboot.

At the same time, I always tested a Mojave login to Mojave - it always worked. I conclude that the server is ok.

Today there was an update (Beta 6) - after that the login worked.

(I haven't yet tested if this works beyond the reboot - I'll report)

Unfortunately, it didn't improve. It's a "working - not working - game". Playing around with the credentials on the server side - change password or login etc. succeeds. Occasionally and arbitrarily …

Worth moving to SMB? Performance difference alone makes it worthwhile.

SMB has been the default and preffered protocol since Mac OS X 10.8.

I recently abandoned AFP (netatalk) and moved to Samba 4.9.5.

It was a pain to determine what the config file really needed (I didn't want netbios/printers/dns/winbind/etc), but I think I got there. Performance is good and Catalina seems to negotiate sensible security options :

NB: Setting "smb encrypt = required" resulted in 40% slower speeds in my experience.

Worth moving to SMB? …

Thanks for this hint and no, I did not yet dive into that. I gave it a fast try but the result is absolutely the same as in AFP …
[doublepost=1567493220][/doublepost]I have found a transitional / emergency solution that is apparently reproducible. I assign a new PW to the user on the server and force that User to set a new PW at the next login. This has helped for now (for a few times).
