netatalk shares mount on OS9, not OS 10.2.8

[Henry Olders]

I have a small home network with a 7200/120 running YDL 3.0.1 and 
netatalk 1.5.5. The directories on this machine can be mounted on a 
PowerCenter running OS 9.1, and also on a Pismo running OS 9.2 as 
classic under OS 10.2.8. When not in classic, OS 10 "connect to server" 
sees the 7200, and sees the shares, but when I attempt to mount them, 
it asks for a username and password, but fails to connect with a "login 
failed" message.

Interestingly, if I first mount the shares under classic, and then 
eject, then force quit classic, I am able to mount the shares under OS 
10. However, if I reboot OS 10, I get the "login failed" message again.

I have verified that AppleTalk is running on OS 10.

Any idea how I can get OS 10 to log in to netatalk?

Thanks for any ideas or help.
