Open Source Document Management System | OpenKM

Hi
I have problem with loging to the OpenKM. I have added a few users (all names contains big letter for example "Tom") then I set system.login.username.lowercase=on and after OKM restart I can't login. When I', writing username "Tom" its changed to "tom" i've got Authentication error, i can't even login as okmAdmin because its changed to okmadmin.
Is there a method to add from commandline user with admin privilege with lowarcase name or maybe there is a method to set system.login.username.lowercase=off? seting this in OpenKM.cfg is not helping

If you re using OpenKM 5.1.x changes in OpenKM.cfg file take no effect, because there are stored in database and handled from Administration. If you want to change any configuration property, you can also access to OpenKM database and modify the proper value in OKM_CONFIG table.

lowecase login enabled must only be used with ldap integration
