SQL server login

[White Tulip]

Hi!
I have a problem, I created an application in Microsoft Access where users have to login with passwords to access the application.
My application tables where at first stored in MsAccess but after sometime, I upsized the application database from MsAccess to Sql server. Now my problem is that users have to login twice to be able to access the application. they have to login first in SQL server Login to access SQl server and then Login into the application to access application. I would love application Users to Login only once. How do I solve this? Please Help!!
Thankyou in advance.

If you're using a windows domain server, have the DBAs set up the database security using those domain accounts.
