Creating user and get the password

Hi all,

I want to create an r/3 user through some coding. I dont want to use transaction SU01. My problem is that I am able to create the user using the BAPIs but its not taking the given password. It's taking logon details as input but I dont get what to pass in that structure. And if it's generating some default password then it should return some value for password.

Can anyone tell me how can i create a user with default password or given password without using any tcode.

Thanks in Advance!
