configuring LDAP with jts using tomcat

but the problem is that I am unable to login into the application using windows credentials. I have to use ADMIN as a user Id as well as password.

please verify my tomcat's server.xml file  parameters shown below,

<realm className="org.apache.catalina.realm.JNDIRealm" <br="">         connectionName="dc=companyname,dc=com"

               connectionPassword="*********"  
       connectionURL="ldap://hostname.com:389" 
               userBase="dc=company name,dc=com" 
               userSearch="(uid={0})" 
               userSubtree="true" 
               roleBase="dc=company name,dc=com" 
               roleSubtree="true" 
               roleSearch="(memberNotAvailablexxx={0})" 
               roleName="cn" 
    />
