Attributes column of the authorization table is to small

[bschoenmaeckers]

The attributes column defined here is to small. It is now only 1000 chars long but on my setup it surpasses that (roughly 1100-1200 chars). You should expand the varchar or consider another type.

Thanks for the report @bschoenmaeckers. I ran into the same. I'll be including a fix for this along with the fix for gh-324 as I'll be expanding the number of characters used even further.
