--- Comment #21 from Dmitry Timoshkov dmitry@baikal.ru --- I don't see anything glaringly suspicious in the grep results.
Is there anything in the terminal when you prepend the 'wine ADExplorer.exe' command with KRB5_TRACE=/dev/stderr ? Also, did you try to login to your AD controller using ldapseach?
