Hello all, I am in the process of setting up OTRS for my organization. We provide tech support to about 20 different organizations and are currently using WebHelpdesk as our helpdesk solution with each customer organization connected to WebHelpdesk with LDAP sync. We would like to accomplish the same thing with OTRS allowing users within the different organizations to login to OTRS with their local AD account. In order to improve the speed of OTRS, I have set up a separate service that syncs AD user information from the various organizations with the OTRS user database. That way OTRS is relying on its own database for user information and it doesn't have to go out over an LDAP connection. I have then set up LDAP authentication so the user is authenticated with AD and the user information is already in the OTRS database. This has been working successfully with the first 10 organizations, but as soon as a user from the 11th organization tries to authenticate, it fails. I know there is hard limit of 10 set for LDAP back ends so I'm assuming that same limit is also on LDAP authentication back ends which is causing the failure. I'm also seeing in the system logs that the 10th organization is the last one OTRS attempts to authenticate against. My question is, does anyone know of a way to override that limit of 10? I've already come up with a successful workaround for the slowness caused by multiple LDAP customer data back ends and we're okay with slower login times due to multiple LDAP authentication sources. Our real goal is a seamless experience for our customers. Any help is much appreciated! Best regards, Nick
