Can you take a screenshot of your LDAP settings and just remove your private info, to see if you have it correctly set?

      settings of ldap plugin??
      I use a LDAP server to connect many services like wiki, owncloud, etc with ldap and its works.
      When I fill in the fields and save when leaving and re-entering, they go blank. It also tells me that it can not connect to the server.

          Default Domain should be your FQDN
          You don't need to put port number after the IP address for LDAP server
          Also, you need to enter the DNS server IP address

              Ok.
              - I put my fqdn and not work yet.
              - I check in my ldap server the fqdn with command:
              hostname --fqdn
              - I put dns server too

              I have doubts with the field "Search Base" but I do not think it's the problem that it does not connect to the server, right?

                  Did you remove the port number after the IP address?

                  Search Base is after you are connected, when you looking for user info

                      ramrajone
                      Yes, i remove port. I show yo the config again:
                      In the terminal i have ping with the server ldap

                          Here are my working settings. I didn't see where you said what ldap server specifics you had (AD, etc).

                          Default Domain: corp.DOMAIN.local
                          DNS Servers: ip of my dns server

                          LDAP Servers: ip address of my primary dc
                          Use TLS: checked

                          Search User: DOMAIN\username.
                          Password: my password
                          Search Base: OU=All_Users,DC=corp,DC=DOMAIN,DC=local
                          LDAP Schema: Microsoft Active Directory

                          My only other suggestion is that you make sure that the user that you are using has privileges to bind to the server.

                            The plugin configuration has been filled correctly and has not given me an error!, and the fields are no longer deleted if I go back in to see their configuration. The problem is when I want to login with the credentials I use ldap I get the error http 500
                            i mean, i near to the problem, but this is new. The settings are ok like my other server with ldap auth.

                              http 500 is pretty generic error. You would have to consult your PHP and Apache error logs to see what the error being logged is.

                                Instead of auto detect can set it manually to MS Active Directory:

                                Also, you might want to try: domainName\UserName
                                Search User:
                                Bind DN (distinguished name) to bind to the LDAP server as in order to perform searches

                                  error.log on nginx:
                                  Stack trace:

                                    You do realize that nginx is not a support webserver for osTicket right?

                                      why not?
                                      I saw users in the forum using osticket with nginx. So that is the problem? Should I use apache?

                                        It does not work out of the box and requires a bunch of configuration changes to make it work. there are a number of threads over on github [if you want to continue using it] that you will need to read through and make configuration changes.

                                        You should use Apache or IIS since we support both.
