Here are some fixes I incorporated into my private copy of
Authen::Smb and Apache::AuthenSmb modules. These changes
are based on some discussion I found in the modperl
mailing list posted on Thu, 16 Sep 1999 by Matt Arnold. I
basically copied Matt's suggestions and added them in.
I was getting the same error messages but after I
incorporated theses changes, it to fixed the problem on
SUN Sparc Solaris 2.5.1..2.8.
=Begin Snippet from mailing list
The resulting additions to Authen::Smb look like this:
use Fcntl qw(:flock);
...
open S, "> /full/path/to/AuthenSmb.lck" or die "Can't open
AuthenSmb.lck: $!\n";
flock S, LOCK_EX;
my $res = Valid_User($username, $password, $server, $backup, $domain);
close S;
In short, I ended up adding
the following two lines to Apache::AuthenSmb.
use Memoize;
memoize('Authen::Smb::authen');
=End of Snippet
I contacted the author of Apache::AuthenSmb (a long time
ago) and asked him if he could add these changes into
the module. He stated he no longer has access to machines
where he can test his module and asked me to post
it in the modperl mailing list (which I never did).
I used this module extensively in our environment and
have also added some other nice features. Anyhow, if
the author can no longer maintain it, i'd be glad ty
update it ;)
Since, this fix also requires that Authen::Smb to be
modified, maybe the author of the cool Authen::Smb module
add some option to allow a lock file or force it to use a
lock file (??).
Something along the lines:
sub authen {
my @args = @_;
# Truncate everything to length 80 to avoid poor coding practices in the
# smbvalid.a (buffer overflows) PMK--fixme in smbvalid.a when possible.
for my $i ( 0..$#args ) {
$args[$i] = substr($args[$i], 0, 80);
}
my($username, $password, $server, $backup, $domain, $lockfile) = @args;
my $res;
if ($lockfile) {
open L, "> $lockfile" or die "Can't open AuthenSmb.lck: $!\n";
flock L, LOCK_EX;
$res = Valid_User($username, $password, $server, $backup, $domain);
close L;
}
else {
$res = Valid_User($username, $password, $server, $backup, $domain);
}
return $res;
}
Anyhow, hope this helps.
