PATCH: rlm_dbm_parser and empty check-items

Hi, I'm trying to use rlm_dbm for authorization, and discovered that the rlm_dbm_parser program won't allow an entry to have an empty check-items list. You can't have, for instance: foo ; ; or foo ; You must have foo some_junk == here ; if foo is to be added to the resulting users.dbm database. To be more precise, you can't have empty check-items AND empty reply-items, which I think one should be allowed to have... :) The attached patch fixes that, and allows rlm_dbm_parser to process a source file with empty check- and reply-items. I created the patch against the latest cvs snapshot (jul. 27). Please apply, or let me know why you think it's a bad idea... :) Thanks, Gabriel
