I'm trying to migrate some nis accounts to RHEL 6 IdM while still keeping the original passwords.

I followed the instructions at: http://www.freeipa.org/page/NIS_accounts_migration_preserving_Passwords

The passwords are in SHA-512 format and I have been testing the migration with commands like this (generated via a script from my nis passwd file) on my IdM server:

$ ipa user-add xxx --first=NIS --last=USER --gidnumber=xxxx --uid=xxxx '--gecos=test account' --homedir=/home/xxxx --shell=/bin/bash --setattr userpassword='{SHA-512}xxxxxxx'

where the xxxxxxx is the hashed password from the NIS password file with the leading $6$ stripped off.

Then I remove nis from the passwd: line in /etc/nsswitch.conf so I'm left with:
passwd:     files   sss

and the account that I migrated cannot log in.

From the sssd log file (below) it looks like its trying to migrate the password but failing with an LDAP authentication failure.

I'd appreciate any pointers to how to find out whats going wrong here.

Accounts which I created manually in the web gui are working ok.

Did you enable migration mode on the IPA server?
