Adding auth_scram_hash: sha does not help.

    Allow to use different hash for storing scram passwords

Spoke too soon, 0c09599d7bc2d9a2ec06da04dc641a8250f56beb will start, but crash on login: https://gist.github.com/licaon-kter/dd98246a58f4b31d8e0cbecefd7e7429

/LE: of course 0371b0f66471c9d340e7a9d8ad96cbfc0def66ed is the winner :)

8214a4fa794855ba6cb91b1b83fa66b6608f1074 still fails to start, log: https://gist.github.com/licaon-kter/02d39c7a1e238e3bbb5f11462ad47487 :(

@licaon-kter Would you be able to start ejabberd debug console on that server (ejabberdctl debug), and see what ejabberd_auth:get_password(<<"YOUR_USERNAME">>, <<"YOUR_SERVER">>). returns? You can replace actual data text in that with xxx or something, i would just like to look how that struct looks in general.

It doesn't look like it's issue with previous scram record format (at least conversion that i added seems to be working correctly here), but maybe there was even older format?

You mean on the old working version at 02cc212f160c45cb119e44438198f4b78344e2d0 ? Sure:

{scram,<<"vGAitxxxxxxxxxxxxxxxxxxxxxxxx">>,
       <<"Zh9vXSjxxxxxxxxxxxxxxxxxxxxxxxxx">>,
       <<"hifZxxxxxxxxxxxxxxxxxxxxxxxxxxx">>,4096}

No joy with 7da81249f8e33e019b2b18b464091f9efef8a30c either

[prefiks]

Ok, you aren't able to start ejabberd with that never version? Still getting error in ejabberd_auth_mnesia:need_transform?

[licaon-kter]

See new log above for the PLuS commit.

[prefiks]

Thanks, I commited some changes to auth_mnesia, which could help, can you give it a try?

[licaon-kter]

Yup, fixed now. Thanks

@licaon-kter, @prefiks: Good job!
