@[deleted]If you want to use the LDAP credentials for the users in osTicket as well, my suggestion is to use the LDAP auth plugin and the HTTP auth plugin in combination to achieve Single Sign On (SSO). Only thing is that you need to set the registration to required and open for everyone. We do this and this way every user gets automatically an account when hitting the "Sign In" button on the osTicket page. Maybe that is also a solution for you ;)Beside, I am not sure if this would also work only with the LDAP plugin (so without HTTP auth plugin), but you could at least try it. If it's working then you would never ever have to register any user again ;)
