smbtad-1.2.6

running an strace on the smbtad, I could figure out that MySQL returns an SQL error.
Looking at the code it is trying to  run the following query:
CREATE TABLE data (vfs_id integer,username varchar,usersid varchar,share varchar,domain varchar,timestamp timestamp,string1 varchar, length integer, result bigint, string2 varchar)

varchar fields need a max length in MySQL, 
Query is accepted if I change all the varchar's to varchar(N)
