[jcifs] Using jcifs to validate users against NT

[Tolman-Kevin]

Hello,

I need to validate user id and password against their NT log in's from a servlet application running on linux/tomcat. I have tried usig jcifs to connect to an NT server using the supplied user id and password and then doing  a SmbFile[] files = file.listFiles();. If a list of files is returned the
userid/password is a valid NT log in and if an exception is thrown I determine that the userid/password  is not a valid NT log in. 

This works except that after three invalid attempts I am locked out. Any subsequent attempts will always fail until a certian time out period passes. I am afraid that if I try this from a servlet app that one user failing to log on will lock up the app for all users. Is this the case? Is there a way
around this? Has anyone else been able to validate a user against NT using jcifs?

I have tried changing all of the properties in the jcifs.prp file but that has not helped.

Any help that anyone could give me would be greatly appreciated.

Thanks
Kevin
