All; As I mentioned last week, I'm setting up a new OTRS 6 instance. I have experience running OTRS 5. In my OTRS 5 instance, we have one agent backend linked to LDAP (Active Directory), and several Customer backends linked to LDAP (Active Directory). For this new instance we'll have several agent backends, linked to LDAP (Active Directory), and we'll use the default behavior for Customers. I've run into an issue where I least expected it, with the LDAP configuration. Here's the message I'm getting: ERROR: OTRS-CGI-64 Perl: 5.16.3 OS: linux Time: Tue Sep 4 08:59:56 2018 Message: Search failed! 000004DC: LdapErr: DSID-0C09075A, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db1 RemoteAddress: 10.2.59.1 RequestURI: /otrs/agent.pl Traceback (31582): Module: Kernel::System::Auth::LDAP::Auth Line: 215 Module: Kernel::System::Auth::Auth Line: 152 Module: Kernel::System::Web::InterfaceAgent::Run Line: 248 Module: ModPerl::ROOT::ModPerl::Registry::opt_otrs_bin_cgi_2dbin_agent_2epl::handler Line: 40 Module: (eval) (v1.99) Line: 207 Module: ModPerl::RegistryCooker::run (v1.99) Line: 207 Module: ModPerl::RegistryCooker::default_handler (v1.99) Line: 173 Module: ModPerl::Registry::handler (v1.99) Line: 32 ERROR: OTRS-CGI-64 Perl: 5.16.3 OS: linux Time: Tue Sep 4 08:59:56 2018 Message: No UserID found for '<username>'!

Does anyone have any pointers on what I might be missing here? Thank you, Dominic L. Hilsbos Director - Information Technology Perform Air International Inc. DHilsbos@PerformAir.com 300 S.
