Unable to login with other users created webusers and system users

Dear All,
I have installed ERPNext on ubuntu server.

I was able to get the main screen and logged in as super administrator.

I went to setup to create other users and created users also by giving email id and other parameters. However when i logged out or tried from other system to login as user. It says password incorrect.

Where should i change the password for user.

Please help me how to login as users after creating users.

Please reply me at srikanthpvs@gmail.com

i logged out, then went to the auto generated website and created users as if i was an outsider, and they work fine.
