[Kea-users] MySQL DB does not work when "lease-database" is set

[Jason Guy]

Hi Kevin,

What version of mysql are you using? I have no problems with mysql 5.7
(client and server). Also, have you initialized the database?

Finally, I assume you are using version 1.1 because that it the only
version available on Debian Apt... I am still trying to have the maintainer
take more of my patches, and push the 1.3 packages to the testing repo, but
it is not going well. If anyone knows the maintainer for this package, or
has any advice about how to get more traction with the debian maintainer, I
would be grateful. I have done a lot of work to patch the 1.1 package to
become the 1.3 package, and I am using in my testing. But I would like to
make this available to all. :)

Cheers,
Jason
