Hi,

I recently upgraded my system from RHEL7 to RHEL8, together with 389ds. Apparently this has caused to upgrade the storage scheme of the user passwords to PBKDF2_SHA256. Everything works fine except freeradius does not support this storage scheme at the moment.

How can I downgrade the storage scheme in 389ds to something that is supported by freeradius in such a way, that doesn't force my users to change their passwords?

Well first you need to change the scheme in cn=config to something like:

     passwordStorageScheme: SSHA512

But if passwords are already in PBKDF2, then you will have to reset those passwords.  There is no undoing it without a full reset of the password at this time.

Yes, that's what the docs say, but a simple bind seems to be enough for me. I tested this and actually I could go back and forth between storage schemes using a simple bind.
In newer versions we do have a "update password on bind", but I didn't think it was in that version and I wasn't sure if it downgraded schemes.  I guess it does :-)
I am very happy with 389ds, its saved my ass...

Great, we really appreciate that!

Cheers,

Mark
