Probable bug in smbd UID switching in HP-UX 10.20

Hi, this is Marco Marongiu from CRS4 Research Center in Sardinia, Italy.

I compiled Samba, versions 2.0.6 and 2.0.7, on an HP J282 server running
HP-UX 10.20. The users authenticate against an NT domain controller and
access to their UNIX home directory; every domain user is also
registered in NIS, and his home directory is shared accross machines via
NFS and automount. Samba server also gives access to three network

Samba works for everything but one. When a new connection is made, the
parent smbd process silently fails to switch its child to the user's
uid/gid. This result in the possibility for every user to delete other
users' print jobs.

I scanned tons of subjects in the samba mailing list archives, searched
deja, read HINTS.txt and compiled 2.0.6 applying the patch "Bug in UID
handling for HP-UX", too: same thing.

I compiled with gcc and native cc also, but results didn't change.

Here is some data you may find useful.

uname -a returns:
HP-UX here_was_my_name B.10.20 A 9000/780 2013314351 two-user license

configure was issued using this command line:
./configure --prefix=/opt/samba-2.0.n --with-automount
when compiling with gcc, and
CC=/bin/cc ./configure --prefix=/opt/samba-2.0.n --with-automount
The "n" in the version number, you guessed that, was 6 when compiling
2.0.6 and 7... ok, that's enough :*)

Ah, yes: the smb.conf (names have been changed and IPs numbers
substituted by x-es).:
