Active directory authentication with Request tracker
I have a single organizational unit in AD server for the purpose of integrating many desktop PC's. Now, I have installed Request tracker v 4.0.8 and integrated it with AD server. Now the issue is, I don't want to authenticate all the user who are in the AD server to RT server. I would like only some of them to authenticate to RT server. Condition is, I don't want to create a new organizational unit. I don't want to create separate user for RT within AD server. I would just like to use the single user name for both desktop integration and for RT purpose. How to achieve this?
