Error in accounting_stop_query when AcctSessionId is longer than 32characters like defined in the database.

Hi, I am using radius 2.0.0-pre0. I encountered following issue. My NAS (radiusclient-ng) sends Accounting requests wich contains AcctSessionId longer than defined in the database which is 32 charaters. When Accounting-Request with Acct-Status-Type:Start arrives to radius the stored record contains the cut parameter. And when there comes the Accounting-Request with Acct-Status-Type:Stop the comparison between AcctSessionId stored in the database always gives negative result. I think there are two solutions, one can increase the column size in the database or change the accounting_stop_query. I am using mysql database. Wating for your feedback. Cheers Tomasz
