Good Day.I just upgraded my OSTicket install from v1.7.x to v1.9.2 The upgrade went smoothly. Afterwards, I installed the Core-Plugins package from: https://github.com/osTicket/core-pluginsI was able to successfully add the LDAP Authentication & Lookup plugin to my OSTicket Install. I then tried configuring the LDAP Authentication & Lookup settings. When I click "Save Changes" at the bottom of the page I'm taken to a blank page with the same URL (using Chrome or Firefox). If I use IE I receive an HTTP 500 - Internal Server error. Any suggestions on how to resolve this? Is there is error in the current version of LDAP Plugin?LDAP Authentication is critical to my setup. I did test some of the other Core-Plugins that were installed; such as HTTP Pass Through. I am able to make & save changes to other plugins. Only LDAP Authentication & Lookup seems to have this problem. My OSTicket installation is running on IIS 7.5 with PHP v5.3Thanks in advance for any assistance you are able to provide!
