Hi list, I'm trying to find out how I could setup OTRS to use a redundant ODBC backend for CustomerUser objects. I initially thought I could setup 2 backends pointing to 2 mirrored mysql servers. But, it seems that OTRS' code dies with a nice HTTP 500 error when a backend isn't available. Has anyone already worked on such a setup? I remember doing such a setup for agents authentication with an LDAP backend using the following in config.pm: # LDAP agent backend my @ldaphosts = ('ldap2','ldap1'); $Self->{'AuthModule'} = 'Kernel::System::Auth::LDAP'; $Self->{'AuthModule::LDAP::Host'} = \@ldaphosts; ... And it seem to work fine at that time. Now, is there an easy solution for ODBC backends? Best regards, Cyrille
