[Samba] PANIC and delayed drive mapping?

[MCCALL,DON (HP-USA,ex1)]

Hi Mike;
2.0.7 defaults 'guest account' to the user nobody, which has a uid of -1 and
gid of -2; 
samba will core on negative uid/gid pairs.  The HPUX version (CIFS/9000)
defaults the 
guest account to 'smbnull' and adds an smbnull user (with positive uid/gid
pair) for this
reason.
to fix this simply add the "guest account = <some valid user made for this
purpose>" to 
the global section of smb.conf

The ioctl error means just what it says - the client requested an ioctl that
we don't 
implement - usually not a big deal; clients will typically get this response
back and fall
back on some other method to accomplish what they wanted to do.

The get share modes error is cleanup from the fact that the previous
connection cored, and 
left information in the sharemodes table.  again no big deal - when you
clean up the 
guest account, this will go away.

Hope this helps,
Don

Hiya!

Samba 2.0.7 on HP-UX 11.0.

When a user tries to map a drive, the smb.log shows the following:

NOTE:  the stanza ending in PANIC repeats 3 times, snipped here for brevity

=====================================================

Question #1:  Why does it "Failed to set gid privileges to (-1,-2) now set
to (0,0) uid=(0,0)"?

Question #2:  What does the "call_nt_transact_ioctl: Currently not
implemented." error imply?

Question #3:  What does the two "get_share_modes" error imply?

TIA,

Mike
