Re: Intermittent issues. Getting the error jcifs.smb.SmbAuthException: Logon failure: unknown user name or bad password.

Mike,

Thanks very much, this makes a lot of sense to me.

I am not sure what has caused the issue in the first place, but I do have it in my list to catch a more detailed exception and log the full stack trace to figure it out if it happens again.

Regards,
Hara

Hi Hara,

I have no idea what the problem is but I should point out that the
Config class should not be used to specify anything that is not static
and global. The Config class is only used to set things that a Windows
client would set in the registry like timeouts, write sizes and and so
on. Meaning you should NOT be specifying credentials using the Config
class. The jcifs.smb.client.{domain,username,password} properties are
the default credentials that the client should use when it cannot find
credentials using any other method. These default credentials are
analogous to the Computer account credentials of a Windows client.

The proper way to supply credentials is to use the
NtlmPasswordAuthentication class and then pass the desired NPA to each
SmbFile constructor.

Mike
