HELP! User Level security With MSAcess

I am developing an application with D3 c/s and MSAccess97 as the back end. I have created userlevel security using MSAccess, but delphi will not allow anyone without Administrator rights to connect to the database. if a person without admin rights tries to connet delphi it asks the person to contact the administrator to give apropriate rights.

How do people with partial rights connect through delphi?

Someone please help, i am stuck on this for more than 5 months now. Note, i am using cached updates.

thanks in advance,

Amal
