[Samba] Help with SMB permissions problems?

[Saul Good]

I compiled a new binary on OS X and now it I'm having a few problems.  
Everything is working just fine including SWAT, but now I have 
permission errors:

I didn't change a thing in my smb.conf, just updated the SMB binaries, 
so what might be wrong this time?  BTW, I symlinked all the new 
binaries to their default locations and renamed the originals *.bak.

It seems i'm having permission problems:

[2003/04/14 13:51:37, 0] lib/util_sec.c:assert_gid(111)
   Failed to set gid privileges to (0,99) now set to (99,99) uid=(0,0)
[2003/04/14 13:51:37, 0] lib/util.c:smb_panic(1094)
   PANIC: failed to set gid

Here is my smb.conf
