Serg's a machine!

Thanks for getting back. The constraint for us is we are on RHEL SCL which provides us MariaDB 5.5.

The extension will get us 90% there for our purposes. For MDEV-6554 you may want to add the ability to prevent 3 or more repeating characters and not match the account id.

I'll see if I can't grab the code and get it to compile for 5.5 unless that's in the works maybe?

Thanks for getting back to me with the good details. Keep up the good work!

Thanks Adam C. Scott

Hi,

I noticed MySQL 5.6 has a validate_password plugin. Since it's

open-source, can we add it to MariaDB 5.5. Or is that bad form, a hot potato, etc.?

...

We need the features of this plugin in our environment, and the PAM

integration is looking not a good "fit" (though it's working great).

...

(I'm trying to get it to compile in right now, but it's having issues

with the includes so far...working on it).

...

So Serg has been working on a validate_password plugin that isn't based on 5.5/5.6 - he's doing it a different way from what I gather

See: https://mariadb.atlassian.net/browse/MDEV-5442

The bonus of how its done now, is that it's here: https://mariadb.atlassian.net/browse/MDEV-6431

It is shipping in 10.1.2 (don't use this in production please) -- see https://mariadb.com/kb/en/mariadb/documentation/plugins/simple_password_chec...

Do you think that will do for you?

An extension to this is tentatively scheduled for 10.2, but this may change if there are enough requests/time to do it -- https://mariadb.atlassian.net/browse/MDEV-6554

It's taken some time, but I have backported the simple_password_check plugin and the password api to MariaDB 5.5 The mysql-test is succeeding on all but the test of the strict_password_validation variable.

My question is, should a pure backport include support for strict_password_validation variable ( https://mariadb.com/kb/en/mariadb/server-system-variables/#strict_password_v...) ? I suspect yes, but wanted to ask to start a further discussion: namely if I submit this patch will it be included in future MariaDB 5.5 releases?

Thank you, Adam Scott

this is currently not in the works, so if you try it and it works, do let us know -- Colin Charles, Chief Evangelist, MariaDB Corporation blog: http://bytebot.net/blog/%7C t: +6-012-204-3201 | Skype: colincharles

Thank you Sergei. I kind of expected that. Was hoping though to get it in upstream for our environment (one can dream!). Colin wanted to know if I got it backported, so I did.

I'll chalk it up to a good exercise :) It would be nice to get us to MariaDB 10 but we have a big commitment to 5.5 right now.

So in this exercise.. : 1) Navigate source code and repos in Git and Bazaar 2) Setup eclipse and cmake to navigate and build MariaDB (I found cscope to be really a powerful tool for getting around code and preferred it over eclipse many times) 3) used gdb to attach and examine values 4) Debug yacc 5) run mysql-test

Thank again, Adam

I believe it's unlikely. If we wanted this feature in 5.5, it would've been implemented in 5.5 in the first place.

But 5.5 is already GA, it was GA for quite a while. We don't add new feature to GA versions, that's why password validation was added to 10.1.

I think that if you'll keep your own version of 5.5 + password validation and use that in your environment - it should not require much efforts to maintain. 5.5 code base is very stable at the moment, changes are few and sql_acl.cc almost doesn't change at all. And then you can skip 10.0 and upgrade directly to 10.1 one day :)
