Hi Pam/Naresh,
Try this T Code:AL08 and SM04 for active users
Try this tables USR02 for User ID lock / validity status
Try this tables : SE16 and enter : "AGR_USERS" to get the list of roles assigned and valid date
Also try this Using : SUIM transaction, select USER --> Users by Complex Selection Criteria --> By Authorization Values --> Execute for criteria and then select Roles.
Thanks
