[Samba] PANIC and delayed drive mapping?

[Kerns, Mike]

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
