[Samba] Mac OS X -- Unable to initgroups. on every anonymous connection.

[Matisse Enzer]

I'm using Samba 2.2.5 on Mac OS X 10.1.5
Connecting to the share "public" with no username or password works 
fine, but, this error message appears in the log every time:

[2002/07/26 15:15:54, 0] smbd/sec_ctx.c:initialise_groups(229)
   Unable to initgroups. Error was Input/output error



What am I doing wrong?


smb.conf file:
[global]
     workgroup = OSXGROUP
     log file = /var/log/samba.log
     max log size = 50 ; maximum of 50Kb in log file
     encrypt passwords = yes
     guest account = unknown

[homes]
         guest ok = no
         read only = no


[public]
     path = /tmp
     read only = no
     comment = Guest Area
     guest ok = yes
