        @Matthieu-Jacquart The mysqli problems you see being thrown look to me to be from an installation, rather than a consistent problem. By installation, I mean something was being requested when web services were active, but mysql or files were being updated. Meaning things simply weren’t “available” when those get thrown into the logs. Those, I think, are non-issues and should be expected but only during the time of updates/upgrades of the fog system. This could also happen in the case of your disk being 100% as the mysql process will usually die without the web server services dying. That does not look to the be the case here.

        I do see the error (get() on line 118 of the DashboardPage.class.php) but that isn’t the problem with AD joining.

          Thanks

          Since I restored my VM, I suppose AD joining will be ok, but the problem is certificate error, hostname changer didn’t work. do you know how to fix it ?
          For information, I install the lastest svn with -C -K argument, after that I downloaded the new client and install it on 2 clients, but always error “Invalid host certificate”

          And now with my own computer (win 10), I’ve got this

              I just had another person report the same “Invalid host certificate” error to me. The one thing I am absolutely positive of is that this is a server issue. I’ll let you know when I learn more.

                I test with removing new client and installing the old one, and everything works fine (hostname changer + AD joining).
                Certificate problem between fog client and fog server…

                  The certificate problem is mostly likely as simple as the srvpublic.crt file is non-existent for whatever reason. I’m unable to replicate. When I push a commit, I update two servers, one running Fedora and one running Ubuntu. Right now they’re Fedora 22 and Ubuntu 15.04 just so I can get as broad as possible in testing the GUI and installer function properly on even “current” releases of OS. Part of the initial installer is the creation of the server’s keys. After that, the only thing that is performed is a certificate generation.

                  I need more info if at all possible.

                      @Matthieu-Jacquart If what I’m reading from the messages is correct, for the authorize section of the log you provided, it’s stating it could not download the .crt file. Followed by, failed to connect to server?

                      Does this sound accurate?

                            The only other thing I can think of them is the client does not have the proper ca certificated stored. This means it cannot verify the servers public key and therefor will not attempt further communication using encryption based protocols. Snapins and maybe printers and possibly all client services beside hostname do not require encryption.

                              @Tom-Elliott I agree with that, question is : how to modidy certificate stored by new client ?

                                @Matthieu-Jacquart There’s a few ways.

                                The easiest way, supposedly, is to simply uninstall the “new client” fog and reinstall. Another way is to go into the Certificate Store and look for FOG CA Certificate. Or whatever it’s labeled as.

                                  For uninstalling/reinstalling client, already did (a lot of time ^^)
                                  With rebbot between, and each time douwnloading client from web interface to be sure it is up to date.

                                  For the other solution, where is the certificate store ?

                                    I just upgraded to 4491 and now the hostnamechanger fails on my clients also with an Invalid Host Certificate. I am running on Red Hat 6.6 and it did work before the upgrade. I have taken one client and uninstalled/reinstalled the new client and it still does not work. I am also seeing problems on previously installed new clients when the hostnamechanger runs on them.

                                      I agree with that, I updated svn each day and trouble began last thursday I think, don’t remember precise svn version at this date.

                                        I have some more information. I deleted the fog certificate and then did a repair on fog and got the message “Failed to download CA certificate”. So it still looks like a problem with the certificate on the server.

                                        Later I uninstalled the fog client, rebooted, and successfully reinstalled it. Still getting the same errors though.

                                          Here is the directory of the fog certificate area on the server:

                                          -rw-r--r-- 1 apache apache  1287 Aug 25 07:51 ca.cert.der

                                          -rw-r--r-- 1 apache apache  4493 Aug 25 07:51 index.php
                                          drwxr-xr-x 2 apache apache  4096 Aug 25 07:51 ssl
                                          [root@clstfogi other]# ls -l ssl
                                          total 4
                                          -rw-r--r-- 1 apache apache 1675 Aug 25 07:51 srvpublic.crt
                                          

                                          It looks like all of the files were regenerated when I reinstalled this morning, unless there is one missing. Are the files being created wrong?
