java - Waffle authentication not working in Windows -

i'm trying use waffle in java tomcat 7 application, authentication windows isn't working.

i have web application works fine, added maven dependency waffle:

<dependency>         <groupid>com.github.dblock.waffle</groupid>         <artifactid>waffle-jna</artifactid>         <version>1.7.4</version> </dependency> 

and added filter in web.xml:

<filter> <filter-name>securityfilter</filter-name> <filter-class>waffle.servlet.negotiatesecurityfilter</filter-class> <init-param>     <param-name>principalformat</param-name>     <param-value>fqn</param-value> </init-param> <init-param>     <param-name>roleformat</param-name>     <param-value>both</param-value> </init-param> <init-param>     <param-name>allowguestlogin</param-name>     <param-value>false</param-value> </init-param> <init-param>     <param-name>impersonate</param-name>     <param-value>false</param-value> </init-param> <init-param>     <param-name>securityfilterproviders</param-name>     <param-value>waffle.servlet.spi.negotiatesecurityfilterprovider</param-value> </init-param> <init-param>     <param-name>waffle.servlet.spi.negotiatesecurityfilterprovider/protocols</param-name>     <param-value>             ntlm             negotiate     </param-value> </init-param> 

<filter-mapping>     <filter-name>securityfilter</filter-name>     <url-pattern>/*</url-pattern> </filter-mapping> 

so, when access page, open login dialog , user logs in. problem i'm seeing when user has logged in once , dialog opens, user needs enter credentials again they're not getting saved. i've tried use waffle save credentials using sso, in console error:

[waffle.servlet.negotiatesecurityfilter] error logging in user: com.sun.jna.platform.win32.win32exception:
