New Comment:
hi,
Thanks for testing :)
I can reproduce the problem with 2k3. One of the ACL problem is that
the SID may not match (even if the usernames are the same). The problem
goes away as long as there are domain users and not users per machine.
A working example is to have a share on windows XP, with full control
to everyone or read only. In both cases is_readable or is_writable will
return the correct results.
However it is not certain that I can restore 5.2's behavior. 5.2 was
using (_)access, which did not do any kind of ACL checks and miserably
fails for 90% of the cases. Its guest was luckily working for remote
shares, but that's not guaranteed to work in every situation. 5.3 and
later actually relies on AccessCheck API to do real ACL checks.
I'm setting up some more test VMs to try to find a solution. Thanks
again for testing, that's very helpful.

ok cmd.exe using runas produces the same results.
testuser is a local user account on each system with the same password.
All clients / servers are in the same domain.
Clients are
Windows XP SP2 GERMAN x86
Windows XP SP3 GERMAN x86
Tested Servers are
Windows 2003 SP2 ENGLISH x64
- is_readable is working here
- Share Permissions test user full control
- Folder ACL test user full control
Windows 2003 SP2 ENGLISH x86
- neither is_readable nor is_writeable is working here
- Share Permissions testuser full control
- Folder ACL testuser full control
Open-E DSS Server (samba)
- everything is fine

Please also tell me which windows you use as server and client.

I'm not sure to see what's the difference with your config.
Questions:
- How did you configure the share (permissions) on 10.1.1.1
- is it a different host than the test machine?
- Pls simply try using runas, I have no idea what runaspc does
internally :). Or simply login using testuser

I extended my test script with further file sys related functions:
if(@!is_dir($folder)) {
echo('FAILED is_dir: ' . $folder . "\n");
} else {
echo "OK is_dir: " . $folder . "\n";
}
if ($dh = @opendir($folder)) {
closedir($dh);
echo "OK opendir: " . $folder . "\n";
} else {
echo('FAILED opendir: ' . $folder . "\n");
}
if(@!is_readable($folder)) {
echo('FAILED is_readable: ' . $folder . "\n");
} else {
echo "OK is_readable: " . $folder . "\n";
}
if(@!is_writeable($folder)) {
echo('FAILED is_writeable: ' . $folder . "\n");
} else {
echo "OK is_writeable: " . $folder . "\n";
}
$filename = $folder . '\\test_' . time() . '.txt';
$content = 'php test ' . time();
if(@!file_put_contents($filename, $content)) {
echo('FAILED file_put_contents: ' . $filename . "\n");
} else {
echo "OK file_put_contents: " . $filename . "\n";
}
if(@!is_readable($filename)) {
echo('FAILED is_readable: ' . $filename . "\n");
} else {
echo "OK is_readable: " . $filename . "\n";
}
if(@!is_writeable($filename)) {
echo('FAILED is_writeable: ' . $filename . "\n");
} else {
echo "OK is_writeable: " . $filename . "\n";
}
if(@!file_get_contents($filename) == $content) {
echo('FAILED file_get_contents: ' . $filename . "\n");
} else {
echo "OK file_get_contents: " . $filename . "\n";
}
if(@!unlink($filename)) {
echo('FAILED unlink: ' . $filename . "\n");
} else {
echo "OK unlink: " . $filename . "\n";
}
all functions are fine expect is_readable and is_writeable:

php-5.3.2-dev-nts-Win32-VC9-x86-200909221530.zip does not help either.
The problem does not occur using samba servers. But it occurs with all
windows severs I have.
I am logged in at my workstation using my normal user account with
admin rights. Then I use RUNASSPC to get a cmd shell.
http://www.robotronic.de/runasspcEn.html
This is my batch file:
rem @ECHO OFF
REM = = = = = MODIFY HERE TO FIT TO YOUR PATH = = = =
SET TESTUNITPATH=D:\php\
SET TESTUNITCOMMAND=c:\php\5.3.2\php.exe test.php
SET ELSDOMAIN=localhost
SET ELSUSERNAME=testuser
SET ELSPASSWORD=testpassword
REM = = = = = DO NOT EDIT BELOW = = = = = = = = = = =
runasspc.exe /program:"%systemroot%\system32\cmd.exe" /param:"/k
%TESTUNITCOMMAND%" /executein:"%TESTUNITPATH%" /domain:"%ELSDOMAIN%"
/user:"%ELSUSERNAME%" /password:"%ELSPASSWORD%"
