Humm, you're right.  While this will probably change in the future, the way to 
fix this for now is to modify the base Authenticator class to have acctUpdate 
return one of the "ACCOUNT_STATUS" constants, and take an additional output 
parameter which will contain the returned error message (if applicable).

Excellent, welcome!

Usually, the way to sent significant patches is as an attachements to a trac 
ticket.  Note that this is in no way meant to discurrage discussing a patch 
on the list.

It really depends on what the fields are and do.  There is a sizeable amount 
of design on how connections are to be limited (time, bandwith) which is a 
completely generic problem.  Depending on the fields the answer will be one 
or more of either:
-Extend the connections table
-Extend the users table
-Create a table specifically for your authenticator,  linked to the users 
table
-Use a Key-Value-Pair style system.

Try to catch me on IRC, or send your proposed fields here for discussion.
