Please, indicate your version of glpi and logs (dev tools of your browser - F12, glpi/files/_logs/*.log). I close for the moment, re-open with precisions |
Do you have some logs in glpi/files/_logs ? or in apache log ? |
There is no log for this problem in the GLPI directory |
What behavior do you use to "upload" your image ? |
Yes when i try with GLPI in localhost it works. And there is nothing in Apache error log. |
Voici un sujet qui parle du même problème. |
Found several links on google who reproduces the issue on another softwares (and with the same plugin for upload) :
This seems to be a problem in Internet Explorer and KB2962872 To be sure, do you ntml authentication on your instance ? |
We use LDAP connection. |
and NTLM auto-logon ? |
Yes we have NTLM auto-logon. I configure GLPI for SSO |
a kb description who seems fix this issue : Can you confirm you have :
|
erf, that kb seems to apply only for IE10... |
So we have to wait for a Microsoft corrective ? |
I just tested with an ntlm environment (apache+winbind) with IE11
Not sure about the security of this, but it seems working |
Hello, |
Look at this post and read from the following comment, you should be able to find a solution: |
Ok thank you , Does the registry key can cause connection problems with software like SharePoint ? |
We have Sharepoint 2007 (in fact MOSS 2007) and I do not notice any problem with it as NTLM is still working. The registry key only disables pre-fetch-authentication which is a mechanism used by IE (and only IE) to from time to time sends NTLM authentication to server (as soon as one page as been using NTLM). |
I check in httpd.conf and i have those directive, it's not NTLM like in the other post but SSPI ( it's a windows server ) <Directory "d:/wamp/www/glpi"> |
SSPI is using NTLM |
We are using Windows servers too. |
Hello, You may have a look into these docs: If you want me to help you in a deeper way, I need your configurations (Server, web server, landscape, ...). thank you |
Hello,
I add directive to allow .htaccess in httpd.conf:
and the registry key : DisableNTLMPreAuth on the client ( If i delete the registry key , sometimes when i upload a document, i have this message " Unauthorized type of file " ) I have test to upload some document and it's working ( with the registry key ) , i will do more test today and give you a feedback :) |
Hello, |
I ask to the sysadmin to add the registry key and it's not possible for us :/ Regards, |
It occurs only with IE !!!
The way to prevent first side of the problem is:
The ways to prevent second side of the problem are:
Regards, |
The registry key is the best option ( force sysadmin :p ). I see in the KB resolution that Microsoft ask to disable Integrated Windows Authentication , is it necessary ? Thank you for your help. Regards, |
Of course the registry key is the best solution as it permits to use NTLM only for the files that really need it (index.php and login.php), such having a big gain of speed for the rest. (NTLM needs an exchange of three challenge/response each time). Regarding KB, don't apply anything else than things I've asked for, as this KB doesn't completely apply to our current case. |
For us the registry options didn't work and neither edge. glpi 0.90.1 on Windows 2008, apache 2.4.4, PHP 5.4.16, NTLM, mod_authnz_sspi davide |
