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

I followed the instructions at:

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?

Yes, I ran:
ipa config-mod --enable-migration=true
on the IPA server.


The has name probably needs to match something in cn=Password Storage

I'd try either {SHA512} or {SSHA512} and see if one of those works better.



I had wondered about the specification of the password hash type.

I chose SHA-512 as it seemed to be suggested in the passwordStorageScheme attribute described in Table 14.1 of the Redhat Directory Server Admin Guide, https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/9.0/html-single/Administration_Guide/index.html. But now I come to re-read that doc it suggests perhaps that SHA covers all the SHA- variants, so I'll give it another go using {SHA}xxxxxxx as the userpassword specification.

I have also seen the userpassword attribute referred to in other places as userPassword and wondered whether the attribute name is case sensitive. Do you know?

Thanks for your input.
