In NetCommunity 7.1, you are importing users from The Raiser's Edge with a User Import. After reaching step 2, you notice the Password section is required, but there is not an option to choose your own password. The screen appears to be display on the autogenerate text with a sample password.
With the security enhancements to NetCommunity 7.1, password encryption was improved. The only option in a User Import is for the system to auto-generate an encrypted password for the record. In order for new users, added from a User Import, to gain access to the site, they will need to visit a page with a User Login part and click the link to reset their password.
